Problem 3/9: Determine D t i the th force f magnitude it d P required i d to t lift one end of the 250 kg crate with the lever dolly as shown. Determine the tension q T in each of the equal length rods which form the two UU shaped members of the device. Problem 3/8: The 600 lb drum is being hoisted by the lifting device which hooks oover er the end lips of the drum. Problem 3/7: What horizontal force P must a worker exert on the rope to position the 50 kg crate directly over the trailer? + ↑ ∑F = 0 : 5T + 500lb − 1000lb = 0 5T − 500lb = 0 5T = 500lb T = 100lb Assumption: Non-verticality of some cables is negligible Problem 3/6: FBD of 1000 lb weight and lower pair of pulleys. Problem 3/6: Withh what Wi h force f g T must the magnitude person pull on the cable in order to cause the scale A to read 500 lb? The weights of the pulleys andd cables bl are negligible State any negligible. ![]() P bl Problems Set 04 S 04 BME 131 BME‐131
