What is the mechanical advantage of the wheel and axle shown below?
2 answers:
Answer:
Mechanical advantage of the wheel and axle is 32.5
Explanation:
Given that,
The radius of the axle,
The radius of wheel ,
We need to find the mechanical advantage of the wheel and axle. It can be calculated as :
MA = 32.5
So, the mechanical advantage of the wheel and axle shown below is 32.5 . Hence, this is the required solution.

<h3>What is diffraction grating?</h3>A diffraction grating is a type of optical instrument obtained with a continuous pattern. The pattern of the diffracted light by a grating depends on the structure and number of elements present.
The given data in the problem is
is the angle formed between the path of the incident light and the diffracted light = 9. 2°
λ is the wavelength of the light=490nm=4.9
N is the number of lines per mm in the diffraction grating=?
n is ordered = 1
The formula for the diffraction grating is;
The number of lines per mm is found as;
Hence the number of lines per mm in the diffraction grating is 326.
