Question

Two blocks with masses M 1 and M 2 hang one under the other. For this problem, take the positive direction to be upward, and use g for the magnitude of the acceleration due to gravity.

B. Find T1 , the tension in the upper rope. Express your answer in terms of some or all of the variables M1 , M2 , and g

C. Find T2 , the tension in the lower rope. Express your answer in terms of some or all of the variables M1 , M2 , a , and g

D. Find T1 , the tension in the upper rope. Express your answer in terms of some or all of the variables M1 , M2 , a , and g

Explanation / Answer

a) When blocks are at rest,
Using equilibrium condition
T2 = M2g and
T1 = T2 + M1g =M2g + M1g
b) When we have an upward acceleration, :
Using equi librium condition
T2 = M2g + M2a = M2 (a +g)
T1 = M2(a+g) + M1(a+g) = (M1 +M2)(a+g)
