Answer:
uniform acceleration motion is a motion with constant acceleration.
Average speed =
(total distance covered)
divided by
(total time spent covering the distance)
Answer:
B. A object in motion stays in motion, and an object at rest stays at rest unless acted upon by a net force.
Answer:
A. Shear stresses are maximum at the neutral axis and normal stresses are maximum furthest from the neutral axis.
Explanation:
Normal stress :
Normal stress is defined as the stress or the restoring force that occurs on the plane when an external axial load is applied on it. For a beam the normal stress is maximum at the point furthest from the neutral axis and is zero at the neutral axis of the beam.
Shear stress :
Shear stress is a stress which occurs when the force acts on the surface of the member in a parallel direction. It changes the shape of the member. For a beam, the shear stress is maximum at the neutral axis.
