An axial member consisting of two polymer bars is supported at C as shown. Bar (1) has a cross-sectional area of 745 mm2 and an elastic modulus of 27 GPa. Bar (2) has a cross-sectional area of 1,550 mm2 and an elastic modulus of 16.8 GPa. Determine the deflection of point A relative to support C.

Two pieces of high-density polyethylene [E = 0.87 GPa] tubing are bonded together and support load P = 140 N. Both tubes are 150 mm long. The outer tube has an outsider diameter of 21.0 mm and an inside diameter of 15.2 mm. The inner tube has an outside diameter of 15.2 mm and an inside diameter of 11.4 mm. Determine the load carried by the outer tube.

A steel [E = 29,300 ksi, α = 6.5×10–6/°F] bar is held between two rigid supports. The bar is stress free at a temperature of 72°F. The bar is then heated uniformly. If the yield strength of the steel is 57 ksi, determine the temperature at which yield first occurs.

A load of P = 555 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,200 ksi] and has a circular cross section with a diameter of 1.01 in. Determine the magnitude of the change in length of bar (1) due to the load. Let a = 34 in., b = 16 in., and c = 8 in.

Find the slope of the line. Type only the numeric answer.y = -3x + 1

A load of P = 8,600 lb is applied to the connection. If the average shear stress in the bolts is limited to 34 ksi and the required factor of safety is 2.2, determine the minimum allowable bolt diameter.

In the food chain, each feeding stage is called what?

A steel [E = 30,600 ksi, α = 6.2×10–6/°F] bar is held between two rigid supports. The bar is stress free at a temperature of 76°F. The bar is then heated uniformly. If the yield strength of the steel is 42 ksi, determine the temperature at which yield first occurs.

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

A load of P = 615 lb is applied to beam ABC. Bar (1) is made of brass [E = 13,000 ksi] and has a circular cross section with a diameter of 1.14 in. Determine the magnitude of the change in length of bar (1) due to the load. Let a = 28 in., b = 13 in., and c = 9 in.
