The structure shown consists of a single member ABCDE with a pin support at A and a roller support at E. Points B and D are at the midpoints of their respective segments. Determine the internal normal force acting on H which are located immediately to the right of B. Take N = 2 kN, O = 5 kN, and P = 5 kN.

The bolt AB in (Figure 1) has a diameter of 18 mm and passes through a sleeve that has an inner diameter of 42 mm and an outer diameter of 52 mm. The bolt and sleeve are made of A-36 steel and are secured to the rigid brackets as shown. If the bolt length is 220 mm and the sleeve length is 200 mm, determine the tension in the bolt when a force of 50 kN is applied to the brackets.

The lifting arm shown below needs to lift a weight of 4 (N). Assuming the links are weightless, determine the magnitude of the force being applied by the pin at B on the lifting arm to the nearest hundredth of a newton. 10Em) 6icm- 150 A Servo Horn Arm 4 (W) 'Servo

Please help. Provide Free Body Diagram, labeled with appropriate quantities to better understand. Also solve. Thank you.

The bars AB, AC, and AD are pinned together as shown in the Horizontal movement of the pin at A is prevented by the rigid horizontal strut AE. Calculate the axial force in the strut caused by the 10-kip load. For each steel bar, A = 0.3 in.2 and E = 29 x 106 psi. For the aluminum bar, A = 0.6 in.2 and E = 10 x 106 psi.
