learning: newtons first law of motion - inertia
question
if a painter is on a horizontal scaffold that is supported by four vertical ropes, the tensions in the ropes
answer
○ are each equal to half the weight of the painter plus the weight of the scaffold
○ are each equal to the weight of the painter plus the weight of the scaffold
○ add to equal the weight of the painter plus the weight of the scaffold
○ cancel to zero
○ i dont know yet

Explanation:

This is a static equilibrium problem. For the scaffold and painter to remain stationary, the sum of the upward tension forces from the four ropes must balance the total downward force, which is the combined weight of the painter and the scaffold. Individual tensions do not need to be equal (unless the load is perfectly symmetric, which is not specified), but their total must equal the total downward weight.

Answer:

add to equal the weight of the painter plus the weight of the scaffold
