Pull 33.0 11.65 . A worker wants to figure P11.65 turn over a uniform, 1250-N, 2.20 m rectangular crate by pulling at 53.0° on one of its verti- 1.50 m cal sides (Fig. P11.65). The floor is rough enough to pre- vent the crate from slipping. (a) What pull is needed to just start the crate to tip? (b) How hard does the floor push upward 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?
