2. An axial rod made of three different materials is fixed between two walls. (You can do this problem without a calculator.) E1 = E = 10 Msi a = a= 10 × 106/°F A1 = A2 = A3 = A = 2 in? Li = L2 = L3 =L = 10 in. E3 = 3E = 30 Msi Oz = 3a= 30 × 10/°F E2 = 2E = 20 Msi O2 = 2a= 20 x 10F The temperature is decreased by 110°F. a) Determine the stress in material1, 61. Specify tension or compression. b) Determine the deflection of point B. Specify – or →. Hint: It may be easier to solve the problem symbolically, in terms of E, a, A, L, AT, and then substitute the numbers at the end. Ans: ơ1 = 36 ksi (T), & = 2.5 x 10² in (→)

Statics and Principles of Moments A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center. 1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left side. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs? 2- Now, another child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum. What are the CW and CCW moment of the seesaw now? What is the net moment and direction? 3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?) 4- Now the fourth child leaves the other three children sitting on the plank. If the three children are sitting in the same potions as they did in part b, the plank would need to move on the seesaw…
1. Note: for part a), you can do this without a calculator; it might be easier to work out the problem symbolically, and then substitute the numbers at the end of the problem. В 2L The axial rod is fixed to the two walls, as shown above. Portion AB is composed of one material (EAB = E), while portion BD is composed of a different material (EBD = 2E). Portion AB has cross sectional area AAB = A, while portion BD has cross sectional area ABD = 2A. EAB = E = 15×106 psi AAB = A = 1 in² EBD = 2E = 30×10° psi ABD = 2A = 2 in² LAB = L = 10 in. LBC = 2L = 20 in. LcD = L = 10 in. An external force, P = 100 kips, is applied at point C as shown below. a) Determine the reaction forces at wall A and D, Ra and Rp. Specify the direction, (→) or (+). b) Deflection at point C. Specify the direction, (→) or (+). (Ans: RA = 100/7 kips →, Rp = 600/7 kips →, & = 1.429x10² in –)
Problem 4: Values: a = 300 mm b = 75 mm c = 100 mm Use the graphical method to break F into components parallel to bars AB and BC. If the component parallel to bar AB is 7 kN, what is the magnitude of F? Comments: B This is a perfect example of why the graphical method is useful - we are asked to resolve a force into components that are not perpendicular to one another. It's difficult to apply regular old sine and cosine (i.e. trig) for this because we're not dealing with right triangles. Instead we will use the law of sines and/or the law of cosines. • Start by drawing a vertical line to represent the vector F. Now draw a line parallel to AB passing through the top of F, and another line, also parallel to AB, through the bottom. Repeat for BC. You should have a parallelogram divided into two triangles by the resultant vector F. Pick one of the triangles to work with, use geometry to figure out the angles, and then apply the law of sines to compute the magnitude of F. Remember, these…
