The jib crane is designed for a maximum capacity of 4 kN, and its uniform I-beam has a mass of 210 kg. Plot the magnitude R of the force on the pin at A as a function of x through its operating range of x-0.2 m tox - 4.8 m. On the same set of axes, plot the x- and y components of the pin reaction at A. Do these plots on a separate piece of paper. Then answer the following questions in Wiley Plus a check for your work. (a) What is the value of R when x - 2.5 m? (b) What is the value of R when x-4.4 m? (c) Determine the minimum value of R and the corresponding value of x.
