A guy-wire supports a pole that is 85 ft high. One end of the wire is attached to the top of the pole and the other end is anchored to the ground 50 ft from the base of the pole. Determine the horizontal and vertical components (in lb) of the force of tension in the wire if its magnitude is 50 lb. (Round your answers to the nearest integer.)

Simple machines can a. increase force only b. decrease force only c. increase or decrease force

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.
