One method of visualizing forces and torques is to use the variable solid blocks. You can vary the length of the cylinder, brick, or sphere radius depending upon the magnitude of the force.
Below you can see the results of a static test where we increase the force applied at the tip of the bucket and display the required force in the cylinders to hold the position. Those arrows were created using Variable Brick Solid blocks. They are part of this submission: Excavator Design Solution in Simscape.
