Center of mass of constant-density plates Find the center of mass (centroid) of the following thin, constant-density plates. Sketch the region corresponding to the plate and indicate the location of the center of mass. Use symmetry whenever possible to simplify your work.

The region bounded by y = sin x and y = 0 between x = 0 and x = π

Expert Solution
Given data

The region is bounded by 0 xπ , 0ysinx. And the area bounded by the graphs of function is,

fx=sinx, gx=0.

where x0,1.

Step 1

Calculate the required area of the region,

A=0πfx-gxdx

Substitute the values in the above equation,

A=0πsinxdx=- cosx0π=--1-1A=2 

Step 2

Calculate the center of mass of thin constant density plates.

x =1A0πxfx-gxdx

Substitute the values in the above equation,

x=120πx sinxdx=12 sinx-xcosx0πx=π2
