A cubic meter of lead which weighs 105 N is submerged in water. The buoyant force acting on it is about
1) the weight of a cubic meter of water, 104 N
2) half the weight of lead, 1/2 × 105 N
3) the weight of lead, 105 N
because
4) the block loses half its apparent weight when suspended in water.
5) the block displaces 105 N of water.
6) the volume of water displaced is one cubic meter.

A cube of polymer that is 0.05 m on each side is to be held in place with a clamp. The clamp is designed to compress the 0.05-m-thick polymer by a constant amount of 0.0001 m to provide the clamping force. The maximum clamping force that is allowable is 1×104 N. To keep the polymer block securely clamped, the clamping force cannot fall below 0.5×104 N for one year, which is the expected life for this device. Assume that this polymer behaves as a Maxwell solid and that the viscous component is Newtonian.
(a) What is the maximum possible elastic modulus in the polymer that will result in the maximum allowable clamping force? (b) Assuming that a polymer is selected that has the highest allowable elastic modulus, what is the minimum allowable viscosity?
