Explanation Given information: Consider the arbitrary body. Consider the three rectangular axes are denoted by x , y , z . The moment of inertia of the body with respect to the x , y , and z axis are denoted by I x , I y , and I z . Calculation: Show the relation for the moment of inertia I y and I z as follows: I y = ∫ ( z 2 + x 2 ) d m (1) I z = ∫ ( x 2 + y 2 ) d m (2) Add Equation (1) and (2). I y + I z = ∫ ( z 2 + x 2 ) d m + ∫ ( x 2 + y 2 ) d m = ∫ ( y 2 + z 2 ) d m + 2 ∫ <

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provi…

A composite pendulum is made of a uniform slender rod and a uniform disk. If the rod has length of 1.0 m and mass of 11.9 kg, and the disk has radius of 0.31 m and mass of 8.0 kg, determine the mass moment of inertia (in kg · m²) about the x'axis that passes through point O (seen from the profile view). Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. G R Profile view Your Answer: Answer
