Question

3. “The effort and load forces would trace out two concentric circles. The wheel is where the effort force is applied, while the axle carries the load force. The radii of each are the effort and load distances. The fulcrum of a wheel and axle system is the center of the wheel”.
Research and find
a. What are concentric circles?
b. What is common in the circles?
c. Do they have the same radii and diameter?

Answer 1

Answer:

a) concentric circles are those circles with same center but different radii

b) center is the common point

c) no

I think this is enough

mark me as a brainlist if you like it

Answer 2

The circles with a common center point are known as concentric circles. In other words. It is defined as two or more circles that have the same center point. Two or more circles that have the same center, but different radii.

a) circles with a common centre

b) centre is common

c) No radii is different.
