The jib crane is designed for a maximum capacity of 10 kN, and its uniform I-beam has a mass of 200 kg.
(a) Plot the magnitude Rof the force on the pin at Aas a function of xthrough its operating range of x= 0.2 m tox= 3.8 m. On the same set of axes, plot the x- and y-components of the pin reaction at A.
(b) Determine the minimum value of Rand the corresponding value ofx.
(c) For what value of Rshould the pin at Abe designed? (Use g= 10 m/s2.)
