Engineering Mechanics

  1. A bar of uniform cross section and weighing 100 N is held horizontally using two massless and inextensible strings S1 and S2 as shown in the figure.

    1. T1 = 100 N and T2 = 0 N
    2. T1 = 0 N and T2 = 100 N
    3. T1 = 75 N and T2 = 25 N
    4. T1 = 25 N and T2 = 75 N
Correct Option: B


T1 + T2 = 100 N
∑ MA = 0

T2.
L
= 100 ×
L
22

T2 = 100 N
T1 = 0 N
