Question details

1-40. Determine the average normal stress in each of the 20-mm-diameter bars of the truss. Set P 40 kN. 1-41. If the average normal stress in each of the 20-mm-diameter bars is not allowed to exceed 150 MPa, determine the maximum force P that can be applied to joint C. 1-42. Determine the maximum average shear stress in pin A of the truss. A horizontal force of P- 40 kN is applied to joint C. Each pin has a diameter of 25 mm and is subjected to double shear. C P 1.5 m 2 m Probs. 1-40/41/42 Show transcribed image textplease just do 1-40
