Determine whether the 15−kg block shown is in static equilibrium under the loadings shown, and report the magnitude of the friction force (in Newton) when P = 770 N and θ = 42 degrees at the state of static equilibrium. The coefficients of static and kinetic friction between the block and the rough inclined surface are shown in the picture. Report the friction force as positive when it is directed downward, and negative when it is directed upwards.

A block of weight W = 200 N on an incline of 20∘ with respect to the horizontal direction is subjected to a constant force P that is inclined by an angle of 30∘ with respect to the horizontal direction, as shown in Figure 3. The coefficients of static and kinetic friction between the block and the incline are μs = 0.30 and μk = 0.20, respectively. a) Draw a free body diagram of the block and find the maximum force P = Pmax that can be applied before the block starts to slide up the incline. Find the normal force N exerted by the incline on the block when P = Pmax . b) For a force P = 500 N, draw a free body diagram of the block and find its (constant) acceleration a up the incline. c) If the block starts from rest at time t = 0 when the force P = 500 N is first applied to the block, find the speed v = v(t) of block and the distance s = s(t) it travels up the incline at any time t.

As shown in the figure, blocks of masses m1 = 268.9 g and m2 = 598.5 g are attached by a massless string over a frictionless and massless pulley. The coefficients of static and kinetic friction between the block and inclined plane are 0.250 and 0.123, respectively. The angle of the incline is θ = 27.1∘, and the blocks are at rest initially. What is the acceleration of the blocks? [Answer with a negative number if m2 moves downward, and a positive number if it moves upward. ] Submit Answer Incorrect. Tries 1 /99 Previous Tries
