The coefficient of friction between block and wedge is μ. Assume all surfaces are smooth. Answer: This is actually more complicated than it might seem. This video contains an excellent analysis to a rather hard problem: A mass resting on a wedge, which itself is free to slide on a horizontal plane. The normal force acts on this block. Answer (1 of 4): In my physics class, while being taught about wedge constraint, I was told that a block kept on a wedge is constrained to move along its surface but I'm can't understand why it is so. Neglecting friction, determine (a) the acceleration of the wedge, and (b) the acceleration of the block relative to the wedge. But is F above the force applied to the wedge, as in the question? Example 8.10 Accelerating Wedge wedge block of mass m A Figure 8.42 Block on accelerating wedge ! Solution. So following forces are a. IF the motion of m is analyzed from ground, its acceleration is A and the forces acting on it are its weight mg and normal reaction N. Asm is at rest, moving with same acceleration as wedge in horizontal direction but in vertical direction, the block is at rest. Block on the incline surface of wedge A has mass m. Mass of A and B are M = 4 m and `M_(0) = 2` m respectively. D. work done normal force (between the block and wedge) on the block from top to bottom is negative. bikramjit das is right ... just use pseudo force ... pseudo forces come into action when tyou need to apply newton's laws in non inertial frame ... F(pseudo) = -ma. A small block m rests on a triangular wedge of mass M and angle , which in turn sits on horizontal table top. In the figure if block `A` and wedge `b` will move with same acceleration, then the magnitude of normal reaction between the block and the wedge will be (The. The block, in general, may have a horizontal component of acceleration. Therefore, their motions are dependent. N 1 is the normal reaction between block and wedge and N 2 the noraml reaction between wedge and ground. If F is very small, then as the wedge and block accelerate to the right, the block will slide down the ramp. 3.4k+ So essentially, I feel as though I have the correct solution, but I am not sure why it is the solution, physically. Where the Q lies. In the figure the wedge is pushed with an acceleration of `sqrt3 m//s ^(2)`. JavaScript is disabled. As block slides down the wedge moves to the left.
