Question #68685

(A) A 2.5m long steel towing bar of solid circular section diameter 50mm is expected to carry a maximum load of 300kN. The factore of safety is 4; and for the steel the UTS is 540Mnm*-2 (to the power of -2) and the modulas of elasticity is 200 GNm*-2.

(I) Calculate the actual towing capacity of the bar and state whether the proposed limit is acceptable.

(II) Determine the extension of the bar under the maximum proposed load.
