A solid square rod is cantilevered at one end. The rod is 0.8 m long and supports a completely reversing transverse load at the other end of ±1.3 kN. The material is AISI 1080 hot-rolled steel. If the rod must support this load for 3 × 104 cycles with a design factor of 1.5, what dimension should the square cross section have? Neglect any stress concentrations at the support end.

Is the initial estimate of the size modification factor 0.85 adequate?

One end of a uniform ℓ = 4.40-m-long rod of weight w is supported by a cable at an angle ofθ = 37°with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod isμs = 0.595.Determine the minimum distance x from point Aat which an additional weight w (the same as the weight of the rod) can be hung without causing the...
