The cross-section of bar BC is rectangular with 40 mm width and 10 mm thickness. A 20 mm diameter bolt at A and a 15 mm diameter bolt at B are used to form a structure as shown above. Determine: The normal stress in bar BC. The shear stress in bolt A and bolt B. 7000 N 7000 N -1m- 1 m- 60° A B 2. The cross-section of bar BC is rectangular with 40 mm width and 10 mm thickness.
