Brad Pitt and Leonardo DiCaprio are cleaning up a movie set. Brad Pitt wants to move a 138.9-kg box onto a moving truck 1.9 m off the ground. (PQYHZFXRKQ).
a) If the box is lifted straight up by Brad Pitt and Leonardo DiCaprio (very strong people), how much force must they apply?
b) How much work have Brad Pitt and Leonardo DiCaprio done lifting the piano onto the truck?
c) If the Brad Pitt and Leonardo DiCaprio only need to apply a force of 389 N to get the piano onto the truck when they use a 13-m long ramp. How much work is done using the ramp?
d) What is the efficiency of the ramp?
e) You should notice that the force needed to life the box in a) is larger than the force needed to lift the box in c). How is it possible that the box can be raised with much less force when the incline is used? (In other words, what is the "trade-off" of using an inclined ramp?)
Explain the difference between "control limits" and "specification limits" in an attributes data setting.
Solve the above problem with parabolic blend such that it accelerates in 1 sec, constant speed in 1 second, and decelerates in the one second. Find position, velocity and acceleration of the joint as a function of time, then plot them. What is the..

An infinite non conducting sheet has a surface charge density σ = +5.80 pC/m2. (a) How much work is completed by electric field because of the sheet if a particle of charge q = +1.60 × 10-19 C is moved from the sheet to a point P at distance d = 3.56..
Calculate the ratio of the drag force on a jet flying at 1140 km/h at an altitude of 10 km to the drag force on a prop-driven transport flying at half that speed and altitude.
Two telephone poles are separated by 40 m and connected by a wire. A bird of mass 0.50 kg lands on the wire midway among the poles, causing the wire to sag 2.0 m below horizontal. Assuming the wire has negligible mass, what is the tension in the wire..
