Consider a uniform bar of length 3.99m and weight 369 N. It is suspended horizontally by two vertical cables at each end. Cable A can support a maximum tension of 639.0 N without breaking, and cable B can support up to 396.0 N. You want to place a small weight on this bar.

a)What is the heaviest weight you can put on without breaking either cable?

c) Where should you put this weight?

c) To strengthen the support of the bar, two more cables that can each support up to 396 N are connected - one from one side of the bar to the bottom of cable b, the other from the other side of the bar to the bottom of cable a (diagonal cables) What is now the heaviest weight you can put on the bar without breaking a cable and where should you put this weight?

In the figure, a uniform plank, with a length L of 5.23 m and a weight of 280 N, rests on the ground and against a frictionless roller at the top of a wall of height h = 1.59 m. The plank remains in equilibrium for any value of θ = 70.0° or more, but slips if θ < 70.0°. Find the coefficient of static friction between the plank and the ground.

A 10kg weight is attached to a wall horizontally via a spring. The rest (equilibrium) length of the spring is 0.2m. The spring has stiffness coefficient k = 50. The weight drags along the ground, giving an effective damping coefficient of b = 40. We will ignore gravity and all other outside forces on the spring. If the weight is pulled to a position 0.5m away from the wall (thus +0.3m past equilibrium) and then flicked toward the wall at...
