Two previously undeformed rod-shaped specimens of copper are to be plastically deformed by reducing their cross-sectional areas.

One has a circular cross section, and the other has a rectangular cross section. During deformation, the circular cross section is to remain circular, and the rectangular cross section is to remain rectangular. Their original and deformed dimensions are as follows:
Circular (diameter, mm) Rectangular(mm)
Original dimensions 18.0 20 x 50
Deformed dimension 15.9137 x55.1

Required:
Which of these specimens will be the hardest after plastic deformation, and why?

hree large plates are separated bythin layers of ethylene glycol and water. The top plate moves to the right at 2m/s. At what sp
MakcuM [25]

Answer: For the center plate to remain stationed in one position without rotating, the bottom plate has to move to the left at a speed of 2m/s, so as to cancel the force acting on it from the top.

The center plate will not move when the bottom plate is moving left in a speed of 2m/s to counter the speed of the top plate, because a body will continue to be at rest if all the forces acting towards the body are equal. The center plate will be at rest because we have directed equal force from the top and bottom of the plate.
