Question
1.4 (A). Twe fork-end pieces are to be joined together by a single steel pin of 25 mm diameter and they are
required to transmit 50 kN. Determine the minimum cross-sectional area of material required in one branch of either
fork if the stress in the fork material is not to exceed 180 MN/m2. What wili be the maximum shear stress in the pin'
[1.39 x 10-m'; 50.9 MN/m]
1.5 (A) A simple turabuckle arrangement is constructed from a 40 mm outside diameter tube threaded internally
at each end to take two rods of 25 man outside diameteT with threaded cnds. What will be the nominal stresscs set up
in the tube and the rods, ignoring thread depth, when the turabuckle carries an axial load of 30 kN? Assuming a
suficient strength of thread, what maximum load can be transmitted by the turnbuckle if the maximum stress is
imited to 180 MN/m?
[39.2, 61.1 MN/m2, 88.4 kN.]
