Question 111 MarkLess force is needed when applied at a farther distance from the pivoted point.AnswerTrue.View full question & answer→
Question 121 MarkMoment of force $=$ force $\times$ perpendicular distance of force $–$ from the pivoted point.AnswerTrue View full question & answer→
Question 131 MarkA force always produces both the linear and turning motions.AnswerFalse. Turning motion depend on Applied force and the perpendicular distance of force from axis $o$ rotation, so if the distance is zero, there is no turning motion.View full question & answer→
