How to do this question ??
The Attempt at a Solution
I know sum of torque and force = 0
at fapplied i got torque = 25sin(45) * 3.8m = 67.18N ..
But don't know what to do next !
k31453 said:ohh crapp i have to use distance from pivot which is 3 right ??
Torque is a measure of the force that causes an object to rotate around an axis. It is measured in units of Newton-meters (Nm). Torque is calculated by multiplying the force applied to an object by the distance from the axis of rotation.
In a static equilibrium problem, the sum of all torques acting on an object must equal zero. To solve for torque, you must first identify all the forces acting on the object and their respective distances from the axis of rotation. Then, use the equation torque = force x distance to calculate the torque of each force. Finally, add all the torques together and set the sum equal to zero to solve for the unknown variable.
Clockwise torque is a force that causes an object to rotate in a clockwise direction around an axis, while counterclockwise torque causes an object to rotate in a counterclockwise direction. The direction of torque depends on the direction in which the force is applied relative to the axis of rotation.
The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. The longer the lever arm, the greater the torque produced by a given force. This means that a force applied farther away from the axis of rotation will have a greater torque compared to the same force applied closer to the axis of rotation.
Yes, torque can be negative. Negative torque indicates that the object will rotate in the opposite direction compared to positive torque. This can happen when the forces acting on an object are unbalanced and create a net torque in one direction, causing the object to rotate in that direction.
