1. Given the figure below, calculate the deflection of the simply supported beam at the center. The material is A36 steel.
2. Given the figure below, calculate the deflection of the simply supported beam at the center. The material is A36 steel and the beam is ten feet long. The concentrated load is at the center of the beam.
3. A square bar that is 50 mm on a side is subject to 25 kN axial tension and a bending moment of 50 kNm. Compute the maximum combined stress. 4. A drive shaft transmits 80 kW of power at 60 rad/s. The drive shaft is 40 mm in diameter. It is also subject to 60 kNm bending moment. Compute the maximum shear stress in the shaft.
5. Design the length of welds for the connection below to resist 100,000 pounds in tension. Plates are 0.5 inches thick and arc A36 steel. The center plate is 6 inches wide and the outer plates are 4 inches wide. Specify the length of 3/8 inch weld and the electrodes used.
6. Given the diagram below, calculate the shear stress in the bolts.
The weight W causes a tension of 100lb in cable CD. If d= 2ft, what is the momentum about the z axis due to the force exerted by the cable CD at point C?
