Question

7. Determine the resultant force FR to replace the load system shown and specify where it acts on the beam, as measured from A. a. Calculate the total force(s) and of the distributed load(s) and determine the location of single force(s) to replace them. (Hint: Analyze the trapezoid-shaped distributed load separately as a rectangular distributed load and a triangular distributed load.) (25%) b. Calculate the moments about A produced by each force, including the 12 kN force and any forces that replaced the distributed load. Add these to calculate the resultant moment about A, MRA.(25%) c. Calculate a single resultant force FR to replace all the loading. (25%) d. Indicate the distance from A on the beam where FR should be located so that MRA is replaced. (25%) 9 kN/m 12 kN 5 kN/m A B 4.5 m 1.5 m
