Q/ A twist of 4 N•m is applied to the handle of the screwdriver. Resolve this couple moment into a pair of couple forces Fexerted on the handle and P exerted on the blade. 4 N-m Ans. F = 133 N 30 mm P = 800 N 5 mm

2-2 A 100-N force is applied at end C of the rod as shown. c) Assess the effect of the angle being varied from 0° to 360° to the moment of the 100-N force about point A. [b) (i) MA=0 N-m; (ii) MA=-24k N-m; (iii) MA=-12k N.m] 2-3 A 600-N force is applied on end D of the bent rod as shown. c) Assess the effect of the angle being varied from 0° to 180° to the moment of the 600-N force about point A.
