A bar has axial loads applied as shown below. A 120 N applied axial load is applied at B, and a 150 Napplied axial load is applied at C. A uniformly distributed axial load, with an intensity of 5 N/m isapplied along the entire length of the bar. а.Calculate the reaction force at A. b. Calculate the internal axial force at a distance of 6 m from the left end of the bar by making acut at x=6 m and applying static equilibrium. с.Plot the axial force diagram.
