9. A concentrated load P is supported by two bars as shown below. Bar (1) is made of cold- rolled red brass [E =16,700 ksi; a =10.4 x 106 /°F] and has a cross-sectional area of 0.250 in.². Bar (2) is made of 6061-T6 aluminum [E= 10,000 ksi;a=13.1 x 106 /°F] and has a cross-sectional area of 0.425 in.². After load P has been applied and the temperature of the entire assembly has increased by 40°F, the total strain in bar (1) is measured as 1,400 μe (elongation). Determine: (a) the magnitude of load P. (b) the total strain in bar (2). | 40° (1) 55°
The top box weighs 125 lbs. and the bottom box weighs 150 lbs. The coefficient of static friction between the boxes is? = 0.6. The coefficient of static friction between the bottom box and the floor is 0.35. What force, P, will cause movement of one or more of the boxes? Does it tip or slip? (Hint: You must determine the minimum force to get the top box to slide; the top box to tip, both boxes to slide, and both boxes to tip. The answer will be the smallest.) 5 ft -3 ft 4.5 ft 4.5 ft B
