Sets R equal to 1.07.

Sets T equal to 125.

Sets P equal to 63.

Calculates cross product and displays R of result.

Displays T of cross product.

Displays P of cross product.

Displays rectangular form of cross product.

The dot product can be used to resolve the force (still in v2) along the axis of the lever.
