56. A forklift is used to offload freight from a delivery truck. Together the forklift and its contents weigh 800 Ib, and the weight is evenly distributed among four wheels. The ramp is inclined 14° from the horizontal. F F1 a. Write the force vector F in terms of i and j representing the weight against a single tire. b. Find the component vector of F parallel to the ramp. Round values to 1 decimal place. c. Find the magnitude of the force needed to keep the forklift from rolling down the ramp. Round to the nearest pound.

3. An object is stuck at the origin. To get the object free, two forces are applied to the object. The first force, F, extends from the origin to position (-8,2). The second force, F2, acts on the object with a magnitude of 8 Newtons in the direction of 30°. You may assume units of distance are in meters. Represent the two force vectors, F and F2, in component form. Leave all answers in exact а. form. b. Draw a sketch of the two force vectors on the graph to the right. -5- с. If these two forces together free the object, in what direction and with what magnitude would the object travel? Round to one decimal -5 place as needed. -5
