- the pliers shown are used to grip a 0.3-in.-diameter rod. knowing that two 60-lb forces are applied to the handles, determine (a) the magnitude of the forces exerted on the rod, (b) the force exerted by the pin at a on portion ab of the pliers.
- Relevant Equations
- 3 reaction equation
I know that moment is distance vector x force vector x the degree between them. I understand it uses the moment about A to solve for the unknown force R. I don’t understand why it use Rx1.2m and why the perpendicular distance between A and R is 1.2m.
could anyone please explain why?
