Fixed point on which a lever rotates
WebIn the mechanism shown in figure 1, the crank AB rotates about A at a uniform speed of 120 rpm in the clockwise direction. The link DC oscillates about the fixed point D which is connected to AB by a coupler BC. The block F moves in the horizontal guides, being driven by link EF. AB=DE=150 mm, BC=CD=450 mm, EF=375 mm Determine i. WebSep 12, 2024 · Figure 10.7. 1: Torque is the turning or twisting effectiveness of a force, illustrated here for door rotation on its hinges (as viewed from overhead). Torque has both magnitude and direction. (a) A counterclockwise torque is produced by a force F → acting at a distance r from the hinges (the pivot point). (b) A smaller counterclockwise ...
