Two identical uniform sticks of mass m and length I are pinned together. They both make an angle with respect to the vertical. A massless string is connected to the bottom of one rod and perpendicularly to the other rod as shown in the figure below. Determine the tension in the string if the table, on which the sticks are located, is frictionless.

A board sits in equilibrium. On the left end, there is a wire that supports the board from the ceiling, and to the right, there is a sawhorse that supports the board from the ground. The sawhorse is a distance d= 1/5l from the right edge of the board. There is a block with mass ms= 4.5kg that is a distance 3/4l from the right edge of the board. Finally the board has a mass mb= 11kg. c) Write down Newton's 2nd law. Put the equation in terms of mb, ms, g, T, and Fn. Where T is the tension in the wire, and Fn is the normal force of the sawhorse on the board. d) Write down Newton's 2nd Law for rotations. Put the equation in terms of l, mb, ms, g, T, and Fn.
4) This Atwood's machine includes two blocks connected by a cable, going over a pulley without slipping. Block 1 (30.0 kg) is connected to a spring (70.0 N/m), and slides on a horizontal surface with a coefficient of kinetic friction of 0.0100. Block 2 is 50.0 kg, and hangs vertically from the cable. The pulley is a disk with a radius of 0.500 m, and its moment of inertia about the center of mass is 10. 0 kg-m“. a) Draw the three free body diagrams, and write out Newton's 2nd Law for each. b) Derive the equation of motion (inhomogeneous 2nd order ODE) for this system. c) Use u-substitution to rewrite this as a homogeneous 2nd order ODE. d) Assume the position x as a function of time t is of the form x(t) = A cos (wt + p) I disk for undamped natural frequency w, phase angle P, and amplitude A. The initial conditions are: x(0) v(0) = -3. 00 m/s. Solve for the position of the mass as a function of time (you need to solve for w, 4, and A). = 2. 00 m and Mz

3.2 Sliding blocks with friction* Mass MA = 4kg rests on top of mass Mg = 5 kg that rests on a fric- tionless table. The coefficient of friction between the two blocks is such that the blocks just start to slip when the horizontal force F applied to the lower block is 27 N. Suppose that now a horizontal force is applied to the upper block. What is its maximum value for the blocks to slide without slipping relative to each other?

or 5, 2. You have a massless spring of force constant 64 N/m, but it is wound tightly enough that you must apply 16 N of force to it before it begins to stretch. You attach a 12 kg mass to one end of the spring. The other end is fixed in place above the mass (e.g. it is clamped to the room's ceiling). A second mass of 1.0 kg is connected to the bottom of this first mass via a thin string of negligible mass. The system is initially in equilibrium, but then the string connecting the smaller mass suddenly snaps. 2.1 What is the initial acceleration of the spring-mass system? 2.2. What is the amplitude of oscillation for this system? 2.3 What would be the period of oscillation for this system? 2.4 Determine the maximum value of the kinetic energy of the mass still connected to the spring. Assume negligible damping.
6.2 In class we noted that the potential energy of a spring is given by Vsp (2) and k the spring constant. Now consider an object of mass m (not attached to the spring) that drops from rest, from a height z; > z0; onto the spring (which is initially in equilibrium at its rest length). Both the gravitational force and the spring force now contribute to the potential energy, initial final k(z – zo)²/2, where zo is the spring's equilibrium point E Zo Z=0 Vgrav Vgrav + Vsp if z z0 V (2) = (1) (a) Sketch (by hand, but carefully) a potential energy diagram for V(2) as a function of height z.
