3. (35 points) For the joint below, determine the maximum allowable fatigue load P for loading from a minimum load of 0.5*P to a maximum load of P. The parts are cast iron. The bolts are steel. No wa...
[3]. (3 marks) Figure below shows a bolted joint subjected to an external force P that fluctuates from 0 to 7 kips The steel bolt specification is 5/8"-11 UNC, SAE grade 5 material with rolled threads. The clamped members are steel of length 1.25 in each (with a total length of 2.5 in). Plain wide washers are utilized at both ends of the bolt. [a]. Using the Goodman line, determine the factor of safety guarding against fatigue failure for the...

1. The section of the sealed joint shown in Fig. Q.1 is loaded by P 6.0 kip. The members have E-16 Mps, All bolts have been carefully preloaded to F. 25 kip a. If hardened-steel washers (American Standard, Narrow) are to be used under the head and nut, what length of bolts should be used (round up to the nearest 0.1 in)? (8 pts) b. Find kb, km (using 30° cone) and C. (24 pts) c Using the modifed Goodman...

A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
