A roll of paper has a uniform weight of 0.75 lb and is suspended from the wire
Question:
A roll of paper has a uniform weight of 0.75 lb and is suspended from the wire hanger so that it rests against the wall. If the hanger has a negligible weight and the bearing at O can be considered frictionless, determine the minimum force P and the associated angle needed to start turning the roll. The coefficient of static friction between the wall and the paper is ?s = 0.25.
30 3 in.
Step by Step Answer:
From minimum P choose 120 o since NA would be smaller than for 60 o Also a comparison co...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
