The moment of inertia of a triangular lamina of mass M about edge AB is equal to? View Solution The moment of inertia of a body is 2.5kgm2. Calculate the torque required to produce an angular acceleration of 18rads−2 in the body. View Solution The moment of inertia of a sphere is...
For continuous distributions, the formula is similar but involves an integral: Second Moment (r = 2) The 2nd moment around the mean = Σ(xi –μx)2. This is equal to the variance. The Σ symbol means to “add up”. See: What is sigma notation? In practice, only the first two ...
Moment, or torque, is a turning force.Moment: Force times the Distance at right angles.You can feel moment when holding onto a fishing rod.As well as holding up its weight you have to stop it from rotating downwards.Example: 120 Newtons of force at 0.3 m M = 120 N × 0.3 m = 36...
