The conical manhole cap is made of concrete and has the dimensions shown. Determine the critical location

Question:

The conical manhole cap is made of concrete and has the dimensions shown. Determine the critical location h = hcr of the pick-up connectors at A and B so that when hoisted with constant velocity the cap is in neutral equilibrium.

Explain what would happen if the connectors were placed at a point h > hcr.

Given:

a = 2 ft

b = 2.5 ft

c = 3 ft

d = 5 ft

e = d − (b − a)
