how to do it in manual, not in matlab.
5) If two plates are fastened by bolted joint, the stiffness of the fastened members or plates (km) is given by: 0.5771Ed km = 2 ln (5 10:5771 + 0.5d 2:50) . Where, E is the Young's modulus of the fastened members, d is the diameter of the bolt, and /is the thickness of the fastened members. Find the value of d that's corresponds to a value of km = 7.5 x 106 lb/in when E= 12 x 106 psi and = 1.5 in. Use secant method with initial approximation of 0.0 and 2.0 for d and ? = 0.001.
