A 140 lb person rides in elevator while standing on a scale that reads in slugs. For each part below, draw a free body diagram, write the equations for Newton’s second law and solve. a.) If the elevator accelerates upward at 2.53 ft/s^2, what is the reading on the scale? b.) If the elevator accelerates downward at 1.53 ft/s^2, what is the reading on the scale? c.) If the elevator moves upward at a constant velocity of 2.53 ft/s, what...

Bob is holding a pineapple in his left hand with his forearm 30 degrees from the horizontal (floor). Draw a free body diagram for the forces and moments on his lower arm. Calculate external forces and moments for this arm segment. Assume: The pineapple weighs 1 kg The pineapple’s weight is located at the center of mass of the hand Distance from the wrist to COM of hand = 0.07m Distance from the wrist to elbow = 0.28m

Suppose you are holding a box in front of you and away from your
body by squeezing the sides, as shown in (Figure 1) .
Part A
Choose the correct free-body diagram showing all of the forces
on the box
What is the force that is holding the box up, the force that is
opposite the weight force?
normal force
kinetic friction force
gravitational force
static friction force
