What force does the spring scale read?

The spring scale simply measures the tension, the magnitude of the force exerted by the string.

What is the magnitude of the force that Earth exerts on the bag?

81 N.
The magnitude of the force that the earth exerts on the bag is 81 N. We’ll use Newton’s second law to determine the weight of the mass.

What must be done to a spring scale before it is used?

2. What must be done to a spring scale before it is used? The scale should be zeroed.

What do the two spring scales read?

Scales read the magnitude of one of the two forces acting on them, the force they exert on the thing they are attached to. So one scale reads the magnitude of the action force the other scale exerts on it. The other scale reads the reaction force.

What can you weigh with a spring scale?

Measure weight or force by hanging objects from the spring scale hook. Measure loose material, such as sand, by pouring it into a plastic bag and hanging the bag from the hook. Dual scales measure from 0-1000 grams or up to 10 Newtons.

What is a force diagram in physics?

In physics and engineering, a free body diagram (force diagram, or FBD) is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a body in a given condition.

What is a spring scale do?

A spring scale or spring balance or newton meter is a type of mechanical force gauge or weighing scale. It works by Hooke’s Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position.

What do you weigh on a spring scale?

Measure weight or force by hanging objects from the spring scale hook. Measure loose material, such as sand, by pouring it into a plastic bag and hanging the bag from the hook. Dual scales measure from 0-1000 grams or up to 10 Newtons. Accuracy is ± 1\%.

How do you make a spring scale?

Experimental Procedure

  1. Hang the spring from a sturdily-mounted hook.
  2. Measure the length of the spring with no weight hanging from it.
  3. Hang a weight from the spring, and wait for it to settle.
  4. Again measure the length of the spring.
  5. Measure the mass of the weight, using the kitchen scale.
