Moment of inertia is diagonal and torques around the axes act independently of each other. When a body is free to rotate around an axis, torque must be applied to change its angular momentum. The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body. Moment of inertia may be expressed in units of kilogram meter squared (kg·m) in SI units and pound-foot-second squared (lbf·ft·s) in imperial or US units. Moment of inertia plays the role in rotational kinetics that mass (inertia) plays in linear kinetics
Landscape of the Body it to us. It informs our understanding of the playwright we know best in terms of his masterpieces, 'Six Degrees of Separation' and 'House of Blue Leaves'. But 'Landscape of the Body' deserves better than it gets here." Landscape of the Body Landscape of the Body is a two-act play by John Guare, first performed in 1977. The play is episodic and non-linear, as it travels back and forth in time. The plot centers on a woman named Betty, whose son, Bert, was recently murdered and decapitated in lower Manhattan. The location of the first and last scenes are the
