) A bar of 20 mm diameter is tested in tension. When a load of 38 kN was applied

extension of 0.12 mm was measured over a length of 200 mm and contraction in

diameter was 0.004 mm. If Young’s modulus is 2 × 105 N/mm2

then the value of

modulus of rigidity is??

8. A stone has an initial velocity of 200 fps up to

the right at a slope of 4 to 3. The components of

acceleration are constant at a x= -12 fps

and ay= -20 fps. Compute the radius of curvature at the

start and at the top of the path.

7. A stone is thrown with an initial velocity of

100 fps upward at 60 to the horizontal. Compute

the radius of curvature of its path at the point

where it is 50 ft horizontally from its initial

position.

A Stone has an initial velocity of 200 ft per see up to the right at a slope of 4 to 3. The components of acceleration are constant at a_x=-12 ft per second² and a_y=-20 ft per second². Compute the radius of curvature at the start and at the top of the path

The Lift Mechanism for the package moving is desired to raise (your registration number)                                        

inch in 2.50sec, remain stationery for 2.0 sec, and return in 2.0 sec. The push mechanism
