A cross-section of a beam is shown in Figure Q2. If the shear force in this section is V = 130 KN, determine the value and the location of the maximum shear stress in the section. In Figure Q2, a = 58 mm and the origin of the coordinate system is at centroid of the cross section. Z A AY 2a O 4a Figure Q2 B a 3a a

The screw of the clamp exerts a compressive force of 250 lb on the wood blocks. The cross section is rectangular, 0.75 in. by 0.50 in 4 in. 0.75 in. a Part A Determine the maximum normal stress along section a- a. Express your answer to three significant figures and include appropriate units. HA ? Omax = 52.8 ksi
