Answer:
Activity 1: Since the only forces apposing the upward movement of the load are gravity and air resistance the formulas of which can both be solved with weight then with constant variables for gravity and air, effort IS directly proportional to weight.
Activity 2:
Inclined plane.
to make lifting easier; raising or lowering a load.
