Calculate the instantaneous elongation if a steel rod of 40 mm and 4 m long subjected to an axial pull of 80 kN. Take E = 2×10? N/mm˛.
If there are redundant constraints in the chain and it forms a statically indeterminate structure, what is the degree of freedom or the mobility of this structure?
Which is the false statement about the properties of instantaneous centre?
If the relative motions of the rigid bodies are in one plane or in parallel planes, then the mechanism is called

Coplanar motion is the motion transformation of any planar mechanism. True or false?
In a mechanical system, if the bodies move in a way such that the trajectories of points in the system lie on concentric sphere, then the mechanism is called
Hooke’s universal joint is an example of spatial mechanism. True or false?
