P1.12 A simple pin-connected truss is loaded and supported as shown in Figure P1.12. The load P is 200 kN. All members of the truss are aluminum pipes that have an outside diameter of 115 mm and a wall thickness of 6 mm. Determine the normal stress in each truss member. Assume truss dimensions of a-12.0 m, b - 7.5 m, and c 6.0 m. FIGURE P1.12

Diameter of pin 2 mm. All pins are in single shear.
Question 1: A light plane structure is supported by a roller at A and a pin at D and is subjected to a load of Pat F as shown in the figure. All the members have rectangular cross section with height 5 mm and thickness 1 mm. Tensile/Compressive strength of the members = 80 MPa, Shear strength of the pin = 50 MPa. Consider an appropriate factor of safety....

1. The members of truss are attached together by pins having 5 cm in diameter and 10 cm in length. The truss is supported by a frictionless pin at one end (joint A) and a roller system at the other joint k). The load Lis equal to 5 kN. The section view of the truss member is below and it is homogeneous all along the truss. Elastic modulus is 200 GPa, shear modulus is 75 GPa for the truss. (a)...
