The structure of the figure is formed by a beam rigid AD held in place by three bars whose dimensions and properties of the material are seen in the figure. Calculate the forces F1, F2 and F3 induced in the bars, when bar (2) cools 100ºF. We are going to assume that the rotation of the AD beam is small, and that the bars are not subject to forces when the system.
According to the data given in the question,

A rigid beam BCD is supported on a roller support at C (4m from B) and has two bars AB and DE attached at each end. The bars can carry either tension or compressive forces. The rigid beam carries a UDL of I kN/m across BC and a point load of P at D as shown in the figure above. The length of the two bars is 3000 mm. The elastic modulus of both bars is 200 GPa and the...

Required Information A steel rod AD and a brass rod BE are connected by a rigid bar ACB, which is fixed at a pivot point. The stiffness of th steel rod is greater than the brass rod. The distances from the pivot point to the connections are 240 mm and 150 mm respectively, as shown in the figure. It is known that rod AD has a cross-section area 41 = 100 mm, length L1 = 330 mm, Young's modulus G...

Figure 1 shows the layout of countershaft used to transmit power to a blower through a pulley drive (4-5). Pulley (driving sheave) 4 has a diameter of 125-mm and pulley (driven sheave) 5 has a diameter of 75 mm. Pulley 5 is mounted vertically below pulley 4 (as shown in the figure). Belt tension on the loose side is 20% of the tension on the tight side. A power of 7.5 kW is transmitted via the gear set (2-3) from...
