A worker wants to turn over a uniform 1220-N rectangular crate by pulling at 53.0 ? on one of its vertical sides (the figure (Figure 1) ). The floor is rough enough to prevent the crate from slipping.
A: What pull is needed to just start the crate to tip?
B: How hard does the floor push on the crate?
C: Find the friction force on the crate.
D: What is the minimum coefficient of static friction needed to prevent the crate from slipping on the floor?

You have a crate full of books with a total mass of 32 kg that you have to move from your bedroom to the door of your apartment using a rope attached to the crate. The coefficient of static friction between the crate and the floor is 0.65, and the coefficient of kinetic friction is 0.45 (a) Pulling the rope horizontally, what is the minimum force you have to pull with to get the crate to start moving? (b) Once...

You are a fitness trainer developing an exercise that involves pulling a heavy crate across a rough surface. You attach a rope to a crate of mass M = 45.0 kg and place it on a carpeted track. Using your physics expertise, you have already determined that the coefficient of kinetic friction between the crate and the carpet is μk = 0.430. To test the apparatus, you have one of your employees pull on the rope as hard as she...

EMCH 212/212H Rigid Body Angular Momentum & Work-Energy Square Crate Tipping Over With Plastic Impact A uniform square crate is released from rest with corner D directly above A and it rotates about A until its corner B impacts the floor and then it rotates about B. The floor is rough enough to prevent slipping and the corner at B does not rebound on impact. Determine, (a) as a function of g and 1, the angular velocity of the crate...
