The screw of the clamp exerts a compressive force of 500 N on the wooden blocks. The cross section at a-a is rectangular and has dimensions 3 cm x 1 cm. GJ 12 cm 0.5cm Icm 3 cm 3cm a. Draw a FBD that includes the cross-section a-a. Include all necessary dimensions. b. Write down the force and moment equations to find the internal loadings at the cross- section. c. Find the state of stress at point B (there is an enlarged version of cross-section a-a to show the location of point B). Point B is located 0.5cm from the bottom. CLEARLY set up your equations (symbol form, then numbers) and explain your work. d. Sketch your final answer on the stress element shown. Write down the values for x, y, and
