Question

The three masses shown in the figure(Figure 1) are connected by massless, rigid rods.

Please express answer using two significant figures and include the appropiate units

Find the coordinates of the center of mass. Find the x-coordinate.

Find the y-coordinate.

Find the moment of inertia about an axis that passes through mass A and is perpendicular to the page

Find the moment of inertia about an axis that passes through masses B and C.

The three masses shown in the figure(Figure 1) are connected by massless, rigid rods. Find the coordinates of the center of mass. Find the x-coordinate. Find the y-coordinate. Find the moment of inertia about an axis that passes through mass A and is perpendicular to the page Find the moment of inertia about an axis that passes through masses B and C.

Explanation / Answer

x = ((0)(100)+(6)(200)+(12)(100))/400

x = 6 cm

y = ((0)(100)+(8)(200)+(0)(100))/400

y = 4 cm

moment of inertia through mass A = 0.0020 kg m^2

moment of inertia through mass B and C = 0.00128 kg m^2

Hopefully these are correct. Let me know!
