Chapter 4 Resultant of Non-concurrent Forces Tutorial 4b 1 Copyright © Rahimah 1. Determine the resultant moment produced by forces F B and F C about point O . Express the result as a Cartesian vector. Ans: M= [-720i + 720 j] N.m 2. Determine the magnitude of the moment that the force F exerts about the y axis of the shaft. Solve the problem using a Cartesian vector approach and using a scalar approach. Ans : M Y = 0.828Nm

Unformatted text preview: A to B is d = 400 mm. Express the result as a Cartesian vector. Ans : M R = [-12.1 i – 10.0 j -17.3 k} N.m 4. Replace the force system acting on the truss by a resultant force and couple moment at point C. FR = 4250 N Ɵ = 61.9 ° (M R ) C = 9.60 kN.m (clockwise) Chapter 4 – Resultant of Non-concurrent Forces Tutorial 4b 3 Copyright © Rahimah 5. The system of four forces acts on the roof truss. Determine the equivalent resultant force and specify its location along AB , measured from point A . F R = 4.52 kN Ɵ = 6.35 ° , Φ = 23.6 ° d= 1.52m...
