A constant torque of 28- nbullm is applied to a grindstone, Ask an Expert

Academics

Q. A constant torque of 28- N•m is applied to a grindstone whose moment of inertia is 0.130 kg•m2. Using energy principles, and avoiding friction, find out the angular speed after the grindstone has made 15 revolutions.

Q. If the crate has a mass of 110 kg and is 1.60 {rm m} tall and 0.8 {rm m} in depth and width, what is the minimum force necessary to make the crate tipping?
