Fhe truss is subjected to the system of forces as shown in the following figure. The truss is supported by a roller at A and a pin at E. The force in member (AB) is equal to. 1000 Ib 1000 Ib 1000 lb 130 B 10 ft 10 n 10n- -10 ft- 1000 lb Select one: a. 1732.1 lb - Tension b. 2598.07 lb - Tension c. 3000 lb - Tension d. 2598.07 lb- compression

In this part, you should base your calculations upon a material of your choice. You have to assume areasonable factor of safety.B.1 Determine the maximum force P that can be supported at joint D .B.2 calculate the cross-sectional area of each member to safely carry the axial load.

The truss is subjected to the loading shown. It is supported by a pin at A and a roller at L. Determine the force in members FH, HG and GI, and state if the members are in tension or compression.

P5 The pin-connected structure shown in the figure consists of a rigid beam ABCD and two supporting bars. Bar AE is an aluminium alloy [EAE 70 GPa] with a cross-sectional area of AAE = 2,400 mm². Bar CF is a bronze alloy [ECF = 100 GPa] with a cross-sectional area of ACF = 6,000 mm². A downward load P=298 kN is applied at point B. Determine the normal stress created in bras AE and CF.
