Sets P equal to 74.

Adds the vectors and displays the resultant R.

Displays T of resultant vector.

Displays P of resultant vector.

Enters resultant vector.

Since the moment equals the cross product of the radius vector and the force vector (r ⋅ F), key in the vector representing the lever and take the cross product.
