The hydraulic cylinder CF, which partially controls the position of rod DE, has been locked in the position shown. Member BD is 16 mm thick and is connected to the vertical rod by a 10 mm diameter bolt. Link AB has a uniform 12 x 12 mm uniform rectangular cross. It is connected to a support at A and to member BD at B by 10 mm diameter pins.
Determine
1. The average normal stress in AB.
2. The average shearing stress in the bolt.
