PROBLEM 2
• An elevator and its load have a total mass of
800kg.Find the tension in the supporting
cable when the elevator or lift originally
moving downwards at 10m/s is brought to
rest with a constant acceleration in a distance
25m
Answer T-9600N.Since T> W the system is
retarding.

ure 5-32). The coefficient of static friction between the
box and the crate is 0.667. The coefficient of static fric-
tion between the crate and the floor is 0.400. Calculate
the minimum force (F) that is required to move the crate
to the right and the corresponding tension (T) in the
rope that connects the box to the wall when the rope is
taut.
