4) A worker is pulling down the rope as shown. If the pulleys in the system are frictionless, and the coefficient of static friction between the 357 40 crate and the floor is µs = 0.3, determine the smallest force the worker must exert on the rope in order to move the 100 kg crate, and the angle 0 at this moment.

Question
A worker is pulling down the rope as shown.
If the pulleys in the system are frictionless, and
the coefficient of static friction between the
crate and the floor is μs= 0.3, determine the
smallest force the worker must exert on the
rope in order to move the 100 kg crate, and the
angle θ at this moment.
4) A worker is pulling down the rope as shown. If the pulleys in the system are frictionless, and the coefficient of static friction between the 35 40° crate and the floor is µs = 0.3, determine the smallest force the worker must exert on the rope in order to move the 100 kg crate, and the angle 0 at this moment.
