1. A log is dragged along the ground using a 120N force on a rope attached to the log and making a 40 degree angle with the ground . Determine the horizontal and vertical components of the force.

2. Calculate the torque when a 100 N force is applied at an angle of 85 degrees to the end of a 60 cm wrench.

3. Two forces of 40 N and 80 N act at an angle of 55 degrees to each other. Find the magnitude and direction of the equilibrant force. (Include a diagram representing the forces)
