More specifically, the multi-hyphenate was born in the Hampstead area of London. Uhm, hi Minghella family? Adopt me pls?!? He grew up in London but studied in the United States As for Max's older sister, Hannah? Well, she just so happens to be the head of motion pictures (!!) at Bad Robot, a role she earned after serving as the president of TriStar Pictures and TriStar Television, per Deadline. He too left his mark in the entertainment industry as an Oscar-winning director behind movies like The English Patient, Cold Mountain, and The Talented Mr. Max's father, Anthony Minghella, sadly died in March 2008 at the age of 54. In the meantime, enjoy this super cute clip of them with the rest of the cast: The actor's also had stints behind the camera as both the writer *and* director of Teen Spiri t, which is how he and Elle originally met-but more on that later □.

The issue would escalate as the vehicle went past 100,000 miles. TSC and check engine lights frequently followed most of the transmission issues. Transmission fluid leaks in this model were too high not to notice. Most of the car complaints reported the issue starting at about 117,000 miles. The 2004 Honda Odyssey had the same transmission failures as its predecessors. Moreover, other customers reported the transmission disengaging on a regular occasion. The repairs for these issues are pretty expensive, exceedingly more than $3100. In addition, customers reported banging noises when shifting gears. Some owners reported that the transmission started failing as early as 10,000 miles.Ī major issue with the transmission system was the rattling and squeaking noises from the section. The high risk of the explosion makes these two years a must avoid as they can injure the passengers and driver in case of an accident. As a result, the model’s sales declined to an all-time low in 2002.Īirbag inflator issues were still present in these models. Unfortunately, Honda did not learn from its past problems and seemed to take little effort into addressing them in these models. The 20 Honda Odyssey had the transmission issues like its predecessors. Minor issues like CEL staying on, Traction Control Warning light malfunctions, and peeling paint also plagued these minivans. This may result in inflator rupture, causing metal fragments to hit the vehicle occupants. The problem statement stated that the airbag was underinflated, which means it won’t protect the vehicle occupants properly. ![]() The transmission also slipped in many vehicles resulting in repairs that cost about $3,300.Ģ000 Honda Odyssey received a recall in 2020 for airbag inflator issues. The transmission issues ranged from rough shifting and other problems like transmission solenoid valve failure in the 1999 model. Unfortunately, most Honda Odyssey vehicles are rated for about 200,000 miles, making these model years a bad purchase. Customers reported many issues with the transmissions, especially after 100,000 miles. However, the four-speed and five-speed transmission models did not lack their faults. The size increased, and the door design became sliding rather than a hinged door. Performance was increased significantly with the help of a 3.5-liter engine. It came with a new five-speed transmission, but the overall design remained the same. The second generation of Honda Odyssey vehicles began in 1999. 2018 – 2019 Odyssey recall is one of the most notable ones despite the vehicles being some of the most reliable today.

FCP does everything I need and then some, and I just don't see any reason to go back to Premiere at all. The last time I did, I got so frustrated with how slow track-based editing was in comparison to what I'd become used to that I came to wonder why I was bothering. I pay for the Creative Cloud subscription because I need a lot of the software that comes with it, so I have access to Premiere myself. There are so many little things that add up to a much superior editing experience that for an independent videographer like myself it's well worth the investment. ![]() It saves a ton of time once you get familiar with it and its quirks, and now I can't imagine editing without things like compound clips, keyword collections, real-time skimming, etc. In my opinion, the magnetic timeline in FCP is one of the best innovations to happen to editing since the first NLE brought it to a computer. I've been editing since the tape-to-tape days, and over the years have used multiple NLE's including Media 100, Premiere and FCP (both classic and X). If your income depends on editing, it very well could be worth the investment as IMO FCP is a far superior editing platform. I'd say that depends entirely on what you're using it for and how easy it is for you to depart with $199. ![]() There are a variety of standards used to define drill sizes, the most common one in the UK is the British Standard BS 328 set which includes twist drill bit sizes between 0.2 mm and 25 mm.īS 328 drill sizes are defined as shown in the drill size chart below: ø0.2 to 0.98 mm: Metric drill sizes are used primarily in Europe and use metric units to measure the drill bit diameter. To get an accurate measurement, use Vernier callipers, but be aware that depending on the quality of the drill bit, there could be a tolerance error of between 5 and 15 thousandths of a unit. Thinner wall thickness can be used because of their smaller thread cross section.To measure the diameter of a drill bit, it’s best to measure the cutting edge rather than the shank (the shank is the part that is held by the drill chuck). ![]() Where length if engagement is limited, they provide greater strength.

The total time of flight of the football is 3.61 seconds. If both sides of the equation are divided by -9.8 m/s/s, the equation becomes 3.61 s = t ![]() By subtracting 17.7 m/s from each side of the equation, the equation becomes -35.4 m/s = (-9.8 m/s/s) The physics problem now takes the form of an algebra problem. By substitution of known values, the equation takes the form of -17.7 m/s = 17.7 m/s + (-9.8 m/s/s) An organized listing of known quantities in two columns of a table provides clues for the selection of a useful strategy.įrom the vertical information in the table above and the second equation listed among the vertical kinematic equations (v fy = v iy + a y*t), it becomes obvious that the time of flight of the projectile can be determined. There are a variety of possible strategies for solving the problem. The solution of the problem now requires the selection of an appropriate strategy for using the kinematic equations and the known information to solve for the unknown quantities. The unknown quantities are the horizontal displacement, the time of flight, and the height of the football at its peak. This is due to the symmetrical nature of a projectile's trajectory. The table also indicates that the final y-velocity (v fy) has the same magnitude and the opposite direction as the initial y-velocity (v iy). This is due to the fact that the horizontal velocity of a projectile is constant there is no horizontal acceleration. In this case, the following information is either explicitly given or implied in the problem statement:Īs indicated in the table, the final x-velocity (v fx) is the same as the initial x-velocity (v ix). The solution continues by declaring the values of the known information in terms of the symbols of the kinematic equations - x, y, v ix, v iy, a x, a y, and t. In this case, it happens that the v ix and the v iy values are the same as will always be the case when the angle is 45-degrees. The solution of any non-horizontally launched projectile problem (in which v i and Theta are given) should begin by first resolving the initial velocity into horizontal and vertical components using the trigonometric functions discussed above. Determine the time of flight, the horizontal displacement, and the peak height of the football. To illustrate the usefulness of the above equations in making predictions about the motion of a projectile, consider their use in the solution of the following problem.Ī football is kicked with an initial velocity of 25 m/s at an angle of 45-degrees with the horizontal. The topic of components of the velocity vector was discussed earlier in Lesson 2. sine(Theta) where Theta is the angle that the velocity vector makes with the horizontal.The initial y-velocity (v iy) can be found using the equation v iy = v i cosine(Theta) where Theta is the angle that the velocity vector makes with the horizontal.The initial x-velocity (v ix) can be found using the equation v ix = v i In each of the above equations, the vertical acceleration of a projectile is known to be -9.8 m/s/s (the acceleration of gravity).Īs discussed earlier in Lesson 2, the v ix and v iy values in each of the above sets of kinematic equations can be determined by the use of trigonometric functions. An application of projectile concepts to each of these equations would also lead one to conclude that any term with a x in it would cancel out of the equation since a x = 0 m/s/s.įor the vertical components of motion, the three equations are The other two equations are seldom (if ever) used. Of these three equations, the top equation is the most commonly used. ![]() For the horizontal components of motion, the equations are You may recall from earlier that there are two sets of kinematic equations - a set of equations for the horizontal components of motion and a similar set for the vertical components of motion. To treat such problems, the same principles that were discussed earlier in Lesson 2 will have to be combined with the kinematic equations for projectile motion. A non-horizontally launched projectile is a projectile that begins its motion with an initial velocity that is both horizontal and vertical. In this section of Lesson 2, the use of kinematic equations to solve non-horizontally launched projectiles will be demonstrated. These equations were used to solve problems involving the launching of projectiles in a horizontal direction from an elevated position. In the previous part of Lesson 2, the use of kinematic equations to solve projectile problems was introduced and demonstrated. |
