PART-A
1) Explain the condition of static equilibrium of a member with (i) two forces
(ii) three forces (iii) two forces and a torque. (3)
2) For the linkage shown in figure, find all constraint forces and torque T required if

F= 120 Nin the direction shown. The dimensions of linkages are as follows.

AB= 60 mm, BC= 180 mm, CD = 120 mm, AD = 80 mm and DE=50 mm. (7)

II 1) Explain sgatic पिल्ल analysis by principle of virtual. work

2) In a four bar mechanism shown in figure torque T3 and T4 have magnitude of 40
Nm and 30 Nm respectively. The link lengths are AB = 250 mm, BC = 600 mm, CD =
350 mm, AD = 700 mm. For the static equilibrium of the mechanism, determine the
required input torque T2.
