Find the magnitude of the constant force F needed to move the mass vertically upwards a distance of 62 mm if x= 228 mm. Assume the pulley is massles and frictionless. The mass is at rest in the initial state and the final state.

A 30kg mass is tied to a uniform rod whose mass and length are 80-kg and 8-m, as shown below. The rod is attached to the floor via a hinge and makes an angle of 70° relative to the ground; a massless string is also attached to the rod at the ¼ point of the rod and makes an angle of 20° relative to the horizontal. What tension must be provided by the rope so that the system remains in stationary? If at some point the string breaks, what will be the angular acceleration of the system the instant that the string breaks?
Problem A block with a mass of 15 kg sits on the smooth incline shown below where the angle is e = 37°. The block is attached to the wall via a spring with a spring constant of k = 246 N/m.

Based on this information, answer the following: a) Determine the distance the spring must stretch to offset the weight component of the block in the x-direction (this is where your x-direction datum will be located). b) Create a free body diagram and use the force balance in the x-direction to develop the second-order ordinary differential equation governing the motion of the block (your force balance should be based upon the datum found in part a). c) Find the natural frequency (wn), the period of vibration (T), and the frequency (f). d) For an undamped, freely vibrating system the solution to the second-order ordinary differential equation developed in part b has the form x(t) = Asin(wnt) + Bcos(wnt).

- H1. A wooden block of mass m is pushed over a floor in a straight line in the x direction with a constant velocity vo > 0. At time t = 0, when the block is at position x = 0, it is no longer pushed and the block experiences only a constant sliding friction force F in the negative x-direction until it comes to rest. (i) Write down the equation of motion of the block for t > 0. Calculate the time, t, at which the block comes to a stop and also find the distance, d, travelled by the block from the time when the pushing is stopped to the time when it comes to rest. (ii) Calculate the work done by the friction force from x = 0 to x = d, and then show that it is equal to the change in the kinetic energy of the block.
The figure shows the Russel fracture traction device and a mechanical model of the leg. The leg is held in balance in the position indicated by the two weights attached to the two cables. The combined weight of the leg and cast is W=180 N. The horizontal distance between points A and B where the cables are attached to the leg is L=100 cm and the vertical distance is d=5 cm. Point C is the center of gravity of the cast and leg at three quarters of the L measured from point A (3L/4= 75 cm). The angle that cable 2 makes with the horizontal is measured as β=30°.
