1. The problem statement, all variables and given/known data You are a member of a medical forensics team investigating a fatal accident at a freight yard. A new crane for lifting cargo broke while lifting a package and the police suspect sabotage. The crane consists of 45.0 kg, 15 ft lightweight aluminum bar supported at its base by a hinge that allows the bar to pivot vertically. A support cable runs from the other end of the bar to the ground. When the hinge failed, the bar was at an angle of 45° to the ground and the support cable was at an angle of 30° to the ground. The yard owner says it is impossible for this to be an accident since the hinge is rated to support a force of three times the weight of the 225 kg package that was being lifted. The package was lifted straight up from the end of the bar at a constant speed. 2. Relevant equations Torque = Force x Length Weight = Mass x Gravity ƩFx = 0 ƩFy = 0 ƩT = 0 T = Torque 3. The attempt at a solution I'm having trouble setting up the picture for this problem. I understand how to solve for forces and am still getting comfortable with torque but I'm having a difficult time drawing out the picture for this problem as I felt like the information given was a bit vague. Any help is appreciated!
