An engineer applies a force of magnitude F=15 N to the tip of a vertical lever. The force has an angle of 60° with respect to the horizontal, as shown in the image below. The distance between point O and the tip of the lever is L-0.25 m. Determine the torque exerted by the force F with respect to an axis that is perpendicular to the plane of the page and that passes through point O. Express your answer in Nm. Make sure you specify in your paper the direction of the torque by indicating if it points into the page or out of the page.

As shown in the figure below, we have a square one meter on a side that is free to rotate about an axis perpendicular to the plane of the square, a distance a from one side and a distance b from the other side. Two forces, F1 and F2, are applied to diagonally opposite corners, and act along the sides of the square, first as shown in case (i) and then in case (ii) of the drawing. In each case, the net torque produced by the forces is zero. If the magnitude of F2 is 6 times that of F1, find the distances a and b that locate the axis. It should be noted that a and b are not drawn to scale. a = ? b = ?

Note: Because the arguments of the trigonometric functions are unitless in this question, your calculator must be in radian mode if you use it to evaluate any trigonometric functions. When powered up, a disk drive starts at rest and spins up with non-uniform angular acceleration according to the following formula: =asin(bt) where a = 708 radians/s2 and b = 1.74 s-1. This lasts for the first 1.81 seconds, after which the drive does not accelerate. How many meters of disk surface have passed underneath the head in 0.79 seconds?
A non-uniform rod of mass M, length L and linear mass density λ = 2x2 is at a rotational equilibrium, shown in the figure*. On the left, mass m1 is hanging from a distance r1 from the wedge. Additionally, r2 denotes the distance between the center of the mass of the rod and the wedge. Derive an algebraic representation for r2 ONLY as a function of M, L, and m1 showing the steps to get there. Hint: first, find Xcm and then find 2 relationships between r1 and r2 *Note: figure is not drawn to scale.
