A rigid member ADE is used to hang a billboard. It is pin connected to another member at C. A and B are pin supports. Member BC can provide up to 5 kN force if it is in tension and 3 kN force if it is in compression. The cables used to support the billboard have a tensile strength of 1 kN. What is the maximum weight of the billboard that can be supported by this structure?

only HANDWRITTEN answer needed ( NOT TYPED)

Required Information The elevation and tit angle of table AB are controlled by an operator's hand at point D. The table supports a box weighing 8.8 Ib with center of gravity at point G. The force applied by the operator is horizonta 18 in. Gil 30 A5 30 10 in. -12 in.- Determine the force the operator must apply to keep the table in equilibrium, and determine the force supported by all members of the machine. The force the operator must apply to keep the table in equilibrium and the force supported by each member of the machine are as follows: TAE lb By Ib By= Ib D= lb

2. Two initially rigid bars AC and DG are pinned at A and G and are also connected by vertical bars BD and CF, each having rigidity = AE. The temperature of bar BD is then raised by an amount AT. 1.5L B D F -2L- Address the following: a. Draw accurate and complete FBD of AC, DG, BD, CF b. Which of a. are two-force members? c.
