5) A 2kg metal bar with 3 meters length is pivoted to the wall on one end and it is attached with a string on the other end to 4 meters above the pivot. A 0.5 kg additional mass is placed on the bar 1.2 meters away from the pivot. Calculate the Tension. Calculate the reaction force of the pivot both as a vector and as magnitude.

A bar of mass m and length L is balanced on a rough wall as shown. The bar is not attached to the wall in any way (i.e. there is no hinge: the bar is just pushing against the wall). Find: the tension of the cable, and the force of the wall pushing on the bar. Hint: Make your x-axis parallel to the bar. What are the forces from the wall on the bar along those axis? never mind

A uniform plank of mass 2.53 kg and length 21.5 cm is pivoted at one end. A spring of force constant 403 N/m is attached to the center of the plank, as shown in the figure. The height of the pivot has been adjusted so that the plank will be in equilibrium when it is horizontally oriented. Find the period of small oscillation about the equilibrium point. Answer in units of s.

A mass of 3 kg is connected to a string of length 3.4 meters to form a yo-yo. It is swung in a vertical circle. The string breaks when the tension in the string is 89 Newtons. It happens to reach this tension on the side of the circle (halfway between the top and bottom) and the mass moves through midair at the velocity it was moving at the side when the string broke. What is the maximum vertical displacement...
