Accepted Answer

Questions on beam deflection and yield point in engineering interview.

Max deflection of a beam with fixed support on one end and flexible support on the other end is calculated using the formula: (5WL^4)/(384EI)
Yield point is the point at which a material starts to deform plastically instead of elastically under stress.
Lower yield point is considered for design because it ensures that the material will not undergo plastic deformation during normal use, which could lead to failure.
For example, in designing a bridge, the lower yield point of the steel used in the construction would be considered to ensure the bridge can support the expected load without deforming.
