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.
U=1/2kx2

The answer is to retain the balance pan clean and to keep chemicals from mixing with other chemicals. Also some chemicals can respond with the metal of the balance pan and cause it to oxidize or corrode. Each time you use the balance pan, use weighing paper or a small dish or beaker to weigh out chemicals.
Hence, the horizontal velocity of the rover is 1.73 m/s
