Question

O 1 02 Impending motion tul Tuu Bi B2 Data provided: m = 15 kg, m2 = 79 kg, js = 0.3, Hk = 0.2, 01 = 132 degrees, O2 = 117 degrees, a = 39 degrees Based on the values provided in the problem (repeated here for your convenience), first compute the magnitude of tension T in the rope attached to Block 1 on the left. Input your value rounded to the nearest Newton in the box provided below. Include the units in your answer. Write your solution on paper and scan for uploading later. Answer:

2. Based on the values provided in the problem (repeated here for your convenience), compute the magnitude of P such that Block 2 is in a state of impending motion down the right slope as shown in the figure.

3. Verify your solution for rope tension T and external force P.

Answer 1

Frictional for = 13.36 N 15 X9.81 147.15N In this numerical, mz > mi Block m, wants to move in upper directin So there will be Kinematic friction will be consider from free body diagram we get R = 147.15 Cos63 = 66.8.0 N and, T+Fs = 47115 Sin 63 2) T 131.11 13.36 117.75 N Tension in scope - T = 117 75 N
