A crate with a weight of 100 N is sitting on top of a crate weighing 200 N. The rope that joints the crates passes around a frictionless pulley at A and a fixed drum at B. If the coefficient of friction is H 0.30 at all surfaces, determine the minimum force P required to start the 200 N crate moving.
MULTIPLE CHOICE, Show your work in the space provided, Circle the correct answer 1. An object is moving with constant non-zero velocity. Which of the following statements about it must be true? As shown in the figure, a woman is straining to lift a large crate, but without success because it is too heavy. We denote the forces on the crate as follows: P is the magnitude of the upward force being exerted on the crate by the person, C...
A woman exerts a horizontal force of 141 N on a crate with a mass of 30.7 kg (a) If the crate doesn't move, what's the magnitude of the static friction force (in N)? (b) What is the minimum possible value of the coefficient of static friction between the crate and the foor? (ASsume the crate remains stationary.) A block of mass 59.1 kg rests on a slope having an angle of elevation of 20.3. If pushing downhill on the...
Review The wedge is used to level the member. The coefficient of static friction between the wedge and the two surfaces of contact is p, = 0.15. Suppose that w = 400 N/m and a =5°(Figure 1) Part A Figure Determine the horizontal force P that must be applied to begin to push the wedge forward. Neglect the weight of the wedge. Express your answer to three significant figures and include the appropriate units. 1 of 1 Ps Value Units...
PLEASE SHOW ALL WORK STEP-BY-STEP AS MUCH AS POSSIBLE 0.75 in 0.75 in. 8.71 A wedge A of negligible weight is to be driven between two 100- ib blocks B and C resting on a horizontal surface. Knowing that the coeffi- cient of static friction at all surfaces of contact is 0.35, determine the smallest force P required to start moving the wedge (a) if the blocks are equally free to move, (b) if block C is securely bolted to...
