The jib crane is designed for a maximum capacity of 15 kN, and its uniform I-beam has a mass of 220 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 to x = 3.7 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 as a check for your work. (a) What is the value of R when x = 0.9 m? (b) What is the value of R when x = 3.6 m? (c) Determine the minimum value of R and the corresponding value of x. (d) For what value of R should the pin at A be designed?
