Question

Using a simple pulley and rope system, a crewman on an Arctic expedition is trying to lower a crate of mass m_1 = 6.69kg.

Option 1: True
Option 2: False

Answer 1

The given statement is true.

Step-by-step explanation:

The student's question relates to physics, specifically to the topic of mechanics and the use of pulleys. A pulley system is a classic example of a simple machine that is widely studied to understand fundamental principles like force, tension, and mechanical advantage. In assessing the efficiency of a pulley system, one must consider factors such as the force applied, the distance over which the force is applied, and the weight of the load being lifted.

Questions like comparing tension in a rope under different accelerations also require understanding of Newton's second law of motion, which relates force, mass, and acceleration.

Atwood machines are a common part of physics curricula and are utilized to illustrate basic concepts in kinetics and dynamics. Questions that involve calculating tensions and accelerations in these systems demonstrate an understanding of how different forces result in the movement of objects with different masses. For a mass that is suspended and in equilibrium, the tension in the rope is equal to the gravitational force acting on the mass.
