- Steel construction beams, with an industry designation of "W12 × 25," have a weight of 25 pounds per foot. A new business in town has hired you to place its sign on a 4.0 m long steel beam of this type. The design calls for the beam to extend outward horizontally from the front brick wall, as shown in the figure. It is to be held in place by a 5.0-m-long steel cable. The cable is attached to one end of the beam and to the wall above the point at which the beam is in contact with the wall. During an initial stage of construction, the beam is not to be bolted to the wall, but to be held in place solely by friction. 5.0 m 4.0 m Tipler & Mosca, Physics for Scientists and Engineers, 6e © 2008 W.H. Freeman and Company fls What is the minimum coefficient of friction beam and the wall for the beam to remain in static equilibrium? What is the tension T in the cable in this case? between the Ms = T = N1Bone has a Young's modulus of about 18 ✕ 109 Pa. Under compression, it can withstand a stress of about 157 ✕ 106 Pa before breaking. Assume that a femur (thigh bone) is 0.45 m long, and calculate the amount of compression this bone can withstand before breaking. in mm
