The left-hand end of a uniform rod of mass 2.00 kgkg and length 1.10 mm is attached to a vertical wall by a frictionless hinge. The rod is held in a horizontal position by an aluminum wire that runs between the right-hand end of the rod and a point on the wall that is above the hinge. The cross-sectional radius of the wire is 2.50 mmmm, and the wire makes an angle of 30.0∘∘ with the rod. What is the length of the wire? Express your answer with the appropriate units. An object of mass 90.0 kgkg is suspended from the right-hand end of the rod. What is the increase in the length of the wire when this object is added? Express your answer with the appropriate units. In your analysis do you need to be concerned that the lengthening of the wire means that the rod is no longer horizontal?
If you bend a rod down, it compresses the lower side of the rod and stretches the top, resulting in a restoring force. Shown is a beam of length L, width w, and thickness t fixed at one end and free to move at the other. Deflecting the end of the beam causes a restoring force F at the end of the beam. The magnitude of the restoring force F depends on the dimensions of the beam, the Young’s modulus Y for the material, and the deflection d. For small values of the deflection, the restoring force is F = [(Ywt3)/(4L3)]dThis is similar to the formula for the restoring force of a spring, with the quantity in brackets playing the role of the spring constant k.When a 70 kg man stands on the end of a springboard (a type of diving board), the board deflects by 4.0 cm.
