The bar is connected to the support using a pin having a
diameter of d = 1 in. If the allowable tensile stress for the bar
is (σt)allow = 20ksi, and the allowable bearing stress between the
pin and the bar is (σb)allow =30ksi, determine the minimum
dimension w so that the bar can hold P=100 kips . Assume the hole
in the bar has the same diameter as the pin.

131 The concrete beam is reinforced with three 20-mm- diameter steel rods. Assume that the concrete cannot support tensile stress. If the allowable compressive stress for concrete is (allown2.5 MPa and the allowable tensile stress for steel is (?allow)st-220 MPa, determine the required dimension d so that both the concrete and steel achieve their allowable stress simultaneously. This condition is said to be 'balanced'. Also, compute the corresponding maximum allowable internal moment M that can be applied to the beam....

Your answer is partially correct. Try again. A simple pin-connected truss is loaded and supported as shown in the figure. All members of the truss are aluminum pipes that have an outside diameter of 4.75 in. and a wall thickness of 0.283 in. Determine the normal stress in each truss member. Assume P = 8 kips, Q = 7 kips, a = 7 ft, b = 10 ft, and h - 9 ft. The stresses are...

Use the method of joints to find the internal forces of each member b. Assuming the maximum allowable tensile stress is 36 ksi and the maximum allowable C. compressive stress is 30ksi what is the required cross sectional area? Assume each member has the same cross sectional area. A 20...
Bar B of the pin connected system is made of aluminum alloy

2) The rigid bar CDE is attached to a pin support at E and rests on the 30-mm diameter brass cylinder BD. A 22-mm-diameter steel rod AC passes through a hole in the bar and is secured by a nut which is snugly fitted when the temperature of the entire assembly is 20°C. The temperature of the brass cylinder is then raised to 50°C while the steel rod remains at 20°C. Assuming that no stresses were present before the temperature...
