It is a good idea to use combination (slip-joint) pliers to loosen and tighten nuts and bolts, since it means not having to carry any wrenches.

A farming cooperative needs to determine which grain storage structure to build. They are considering two designs: Structure A – Inverted Truncated Granary (Truncated Cone): The truncated cone is the shape of a traditional cone with a certain portion removed. The theoretical height from the point to the base is 13.9 m with a radius of 3.66 m. The truncated portion is 3.11 m high from the point to the base with a radius of 0.88 m. The design is inverted to maximize grain removal. Structure B – Traditional Silo (Cylinder with Hemispherical Dome): The traditional silo features a cylindrical main section with a radius of 2.43 m and a height of 8.21 m. Atop this cylinder sits a hemispherical dome with the same radius of 2.43 meters. This design is simple, but wants to maximize the storage The cooperative plans to store primarily wheat, which has a density of 770 kilograms per cubic meter, though they may also store corn at 720 kilograms per cubic meter. The foundation and floor of either structure can safely support a maximum loading of 450,000 kilograms without risk of structural failure. What is the amount of force that the mass of the grain is exerting on the floor.

An artillery platform tested at Aberdeen Proving Grounds is evaluating a new explosive charge. The 25.6 kg shell is fired from a platform 31.8 m above sea-level at an angle of 37.2° above the horizontal. The muzzle velocity is 600 m/s and lands at a height of 10.2 m. Assuming no air resistance and using g = 9.81 m/s². How much further would the projectile have gone if it contained 9 % more kinetic energy?
