Lamina a lamina of arbitrary shape rotates freely under zero torque. (a) use euler's equations to show that the sum is constant if the 1, 2 plane is the plane of the lamina. (this means that the projection of w on the plane of the lamina is constant in magnitude) (b) what kind of lamina gives us = constant as well?

yup its correct its: c) b b

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
