An aluminum [E = 10,000 ksi] control rod with a circular cross section must not stretch more than 0.23 in. when the tension in the rod is 2,200 lb. If the diameter of the rod is 0.378 in., determine the maximum length of the rod.

An aluminum [E = 10,000 ksi] control rod with a circular cross section must not stretch more than 0.20 in. when the tension in the rod is 2,000 lb. If the diameter of the rod is 0.370 in., determine the maximum length of the rod.

Two pieces of high-density polyethylene [E = 0.86 GPa] tubing are bonded together and support load P = 105 N. Both tubes are 150 mm long. The outer tube has an outsider diameter of 21.0 mm and an inside diameter of 16.2 mm. The inner tube has an outside diameter of 16.2 mm and an inside diameter of 12.2 mm. Determine the load carried by the outer tube.

The bell crank shown is supported by a single shear pin connection at B and a roller support at C. An external load of P = 1,750 lb at an angle of θ = 38° acts on the bell crank at A. The pin at B has a diameter of d = 1.125 in., and the ultimate shear strength of the pin material is σU = 64,000 psi. Use dimensions of a = 11.0 in. and b = 5.5 in.What is the factor of safety of pin B with respect to its ultimate shear strength?

An aluminum [E = 10,000 ksi] control rod with a circular cross section must not stretch more than 0.24 in. when the tension in the rod is 2,300 lb. If the diameter of the rod is 0.374 in., determine the maximum length of the rod.

An axial member consisting of two polymer bars is supported at C as shown. Bar (1) has a cross-sectional area of 675 mm2 and an elastic modulus of 30 GPa. Bar (2) has a cross-sectional area of 1,600 mm2 and an elastic modulus of 16.2 GPa. Determine the deflection of point A relative to support C.

Axial deformation in a bar loaded in the axial direction can be reduced by which of the following?

A steel [E = 30,400 ksi, α = 6.4×10–6/°F] bar is held between two rigid supports. The bar is stress free at a temperature of 74°F. The bar is then heated uniformly. If the yield strength of the steel is 60 ksi, determine the temperature at which yield first occurs.

A load of P = 9,700 lb is applied to the connection. If the average shear stress in the bolts is limited to 29 ksi and the required factor of safety is 2.2, determine the minimum allowable bolt diameter.

A load of P = 6,000 lb is applied to the connection. If the average shear stress in the bolts is limited to 32 ksi and the required factor of safety is 1.8, determine the minimum allowable bolt diameter.
