System of Parti...

Three identical uniform rods each of length 1 m and mass 2 kg are arranged to form an equilateral triangle. What is the moment of inertia of the system about an axis passing through one corner ans perpendicular to the plane of the triangle:-

A point at which a whole weight of body act vertically downward is ________.

Two identical uniform rod each of mass $$m$$ and length $$l$$ joined perpendicular to each other. An axis passes through junction and in the plane of rods. Then $$M.I.$$ of system about the axis is 

A uniform rod of length of $$1$$m and mass of $$2$$kg is attached to a side support at $$0$$ as shown in the figure. The rod is at equilibrium due to upward force T acting at P. Assume the acceleration due to gravity as $$10m/s^2$$. The value of T is?

Find the velocity of centre of mass of the system shown in the figure

A block of mass $$m$$ having coefficient of friction $$\mu$$ with the floor $$F$$ is placed at one end of the spring. The spring is attached to this block and a vertical shafts. The floor with the shaft is given an angular acceleration $$\alpha$$ Then:

Mark correct option or options:

A shown in figure two uniform rods of mass M and length L each are joined . what is the moment of inertia of system about an axis perpendicular to plane through end A?

$$L=I\omega$$ formula is:

Ram says, $$'A$$ body may be in pure rotation in the presence of a single external force, 'Shyam says, 'This is possible only for a rigid body', then:
