Question

A metal sheet 14cm * 2cm thickness is cut into 2 equal pieces of width 2 cm and are laid along x-y plane as shown. the centre of mass has coordinates.

Answer 1

Given: A metal sheet 14 cm * 2 cm thickness is cut into 2 equal pieces of width 2 cm and are laid along x-y plane .

To find: the center of mass has coordinates ?

Solution:

• Now we have given  metal sheet 14 cm * 2 cm thickness is cut into 2 equal pieces of width 2 cm and are laid along x-y plane .

• Lets assume it is cut parallel to 14 cm side.

• Then center of mass of the system will be:

                   (0.5 + 7 / 2 , 7 + 0.5 / 2 , 0.5 + 1.5 / 2 )

                   (3.75 , 3.75 , 1)

                   So x = 3.75 cm, y = 3.75 cm , z = 1 cm.

Answer:

        So center of mass is at:  (3.75 , 3.75 , 1)

Answer 2

Answer:

x=3.75

y=3.75

z=1

hope it helps you
