A dumbbell-shaped object is composed by two equal masses, m, connected by a rod of negligible mass and length r. If I1 is the moment of inertia of this object with respect to an axis passing through the center of the rod and perpendicular to it and I2 is the moment of inertia with respect to an axis passing through one of the masses we can say that

Relation between two moment of inertia is

Explanation:

Here we know that moment of inertia of the object from an axis passing through mid point and perpendicular to the plane is given as

now moment of inertia about an axis passing through one of the mass is given as

now we have

compass can be used day and night, cloudy or sunny

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
