Equations: Net torque=0=Net force
I believe this is a static equilibrium question but can't figure out how to do it
ah got it thank youDelta² said:You get involved with the forces along the line of the 80Kg rod, that's not what you should do, the x-axis is not the line of the 80Kg rod, the first picture at OP shows which are the x -axis and the y-axis.
In the y-axis you got the weights of the rod and the mass m, 80Kg and 10Kg respectively (and the F_y component of the force from wall at A).
In the x-axis you got F_x and the tension T from the cable.
Static equilibrium refers to a state where an object is at rest and experiencing no changes in its motion. It occurs when the sum of all forces acting on the object is equal to zero and the sum of all torques acting on the object is also equal to zero.
A moment is a turning effect caused by a force acting on an object at a certain distance from a fixed point. In the context of static equilibrium, moments are used to determine the distribution of forces and their effects on an object.
To calculate moments, you must multiply the magnitude of the force by its distance from the pivot point. The direction of the moment is determined by the direction of the force, with counterclockwise moments being considered positive and clockwise moments being considered negative.
The conditions for static equilibrium are that the sum of all forces acting on the object must be equal to zero, and the sum of all torques acting on the object must also be equal to zero. This means that the object will not move or rotate unless an external force is applied.
The principles of static equilibrium can be applied to solve a variety of problems in engineering, physics, and other fields. For example, they can be used to analyze the stability of structures, determine the forces acting on a bridge or building, or design machines and other mechanical systems. By understanding static equilibrium, scientists and engineers can create safer and more efficient structures and devices.
