Mass Moment of Inertia

Moment of Inertia of a body depends on the distribution of mass in the body with respect to the axis of rotation For a point mass the Moment of Inertia is the mass times the square of perpendicular distance to the rotation reference axis and can be expressed as I = m r 2 (1) where I = moment of inertia

How to Calculate Elongation

Knowing how an object will elongate is critical for designing machines that will operate under stressful conditions Insert the values into the equation Elongation = P * L / (A * E) In the example multiple ten times five to get fifty and multiple 3 14 times twelve to get 37 68 Divide fifty by 37 68 and get an elongation of 1 33 inches
