Answer:
Step-by-step explanation:
The two force F1 and F2 are represented by vectors with initial points that are at the origin.
the terminal point of the vector is point P(1, 1, 0)
Therefore, the direction of the vector force is
The unit vector in the direction of force will be
The magnitude of the force is 40lb, so the force will be
The terminal point of its vector is point Q(0, 1, 1)
Therefore, the direction of the vector force is
The magnitude of the force is 60lb, so the force will be
The resultant of the two forces is
The magnitude force will be
to (1 decimal place)=55.7lb
b) The direction angle of force F
The angle formed by F and x axis
The angle formed by F and y axis
The angle formed by F and z axis
