A cargo airpolane has a maximum takeoff ...

A cargo airpolane has a maximum takeoff weight of 19,000 kilograms. The airplane, crew, and fuel have a combined weight of `14,750` kilogrms. The airpolne will be loaded with n identical cargo containers, each of which has a weight of 125 kilograms. What is the greatest value of n such that the airplane does not exceed its maximum takeoff weight ?

The correct Answer is:
B

You're given the weight of every ting on the airplane except the combined weitht of the cargo containers and you're given the maximum takeoff weith of the plane. Therefore, the difference between the maximum takeoff weight and the weight of the plane, crew, and fuel must be the maximum combined weith of the cargo containers.
You're also told that n represents the numbers of cargo containers that will be loaded on the plane and that each container weight 125 kilograms. You need to find the number of containers, n, that make up the difference in weights.
The maximum takeoff weight of the plane is 19,000 kilograms and the weight of the plane, creq, and fuel is 14,750 kilograms. Hence, the maximum number of cargo containers can have a combined weight no greater than `10,000-14,750=4,250` kilograms. That means that the maximum number of containers, n must be 4,250 kilograms `div125` kilograms =34 containers. Thus, (B) is correct.

The posted weight limit for a covered wooden bridge in Pennsylvania is 6000 pounds. A delivery truck that is carrying x identical boxes each weighing 14 pounds will pass over the bridge. If the combined weight of the empty delivery truck and its driver is 4500 pounds, what is the maximum possible value for x that will keep the combined weight of the truck, driver, and boxes below the bridge’s posted weight limit?

An amusement park ride consists of airplane shaped cars attached to steel rods. Each rod has a length of 20.0 m and a cross-sectional area of 8.00 cm^(2) . Young's modulus for steel is 2 xx 10^(11) N//m^(2) . a. How much is the rod stretched (in mm ) when the ride is at rest ? (Assume that each car plus two people seated in it has a total weight of 2000 N .) b. When operating, the ride has a maximum angular speed of sqrt(19/5) rad//s . How much is the rod stretched (in mm) then?

Direction : Resistive force proportional to object velocity At low speeds, the resistive force acting on an object that is moving a viscous medium is effectively modeleld as being proportional to the object velocity. The mathematical representation of the resistive force can be expressed as R = -bv Where v is the velocity of the object and b is a positive constant that depends onthe properties of the medium and on the shape and dimensions of the object. The negative sign represents the fact that the resistance froce is opposite to the velocity. Consider a sphere of mass m released frm rest in a liquid. Assuming that the only forces acting on the spheres are the resistive froce R and the weight mg, we can describe its motion using Newton's second law. though the buoyant force is also acting on the submerged object the force is constant and effect of this force be modeled by changing the apparent weight of the sphere by a constant froce, so we can ignore it here. Thus mg - bv = m (dv)/(dt) rArr (dv)/(dt) = g - (b)/(m) v Solving the equation v = (mg)/(b) (1- e^(-bt//m)) where e=2.71 is the base of the natural logarithm The acceleration becomes zero when the increasing resistive force eventually the weight. At this point, the object reaches its terminals speed v_(1) and then on it continues to move with zero acceleration mg - b_(T) =0 rArr m_(T) = (mg)/(b) Hence v = v_(T) (1-e^((vt)/(m))) In an experimental set-up four objects I,II,III,IV were released in same liquid. Using the data collected for the subsequent motions value of constant b were calculated.
