What is the CG of a semicircular Lamina?

Explanation: The centre of gravity of a semi-circle lies at a distance of 4r/3π measured along the vertical radius.

What is the Centre of mass of a semicircle?

Hence, the center of mass of a semi circular ring lies on the vertical passing through its center of curvature at a distance of 2Rπfrom the center of curvature.

What is the position of Centre of mass of semicircular disc?

If we consider a circular disk, then its centre of mass lies at the centre of the disk but when we consider a semicircular disk its centre of mass shifted to above in the y-axis as shown.

What is the center of mass of a lamina?

The center of mass is also known as the center of gravity if the object is in a uniform gravitational field. If the object has uniform density, the center of mass is the geometric center of the object, which is called the centroid. Figure 15.6. 1 shows a point P as the center of mass of a lamina.

What is the centre of mass of a sphere?

A sphere is a uniform figure hence center of mass will lie where the symmetrical axis intersects with another symmetrical axis. We know that center of mass lies on the symmetrical axis, A ring is a uniform figure hence center of mass will lie where the symmetrical axis intersects with another symmetrical axis.

What is the Centre of gravity of the lamina?

The center of gravity of a lamina is the point that intersects the lines of action of multiple forces that each individually act to suspend the lamina at equilibrium.

How do you find the CG of a hemisphere?

Centre of Mass of the solid hemisphere, yc = 3R/8, Here R is the radius of the hemisphere.

Where does the centre of mass of uniform triangular lamina lie?

centroid
The center of mass of the triangular lamina is at the centroid which is the point of the intersection of medians.
