1. Find (and illustrate with a sketch ) a pair of forces which is equipollent to the couple in the figure,and has one force equal to 50i N through the point (x, y) = (10, 20) cm.

2. Repeat the preceding problem with condition changed to a force of 180j N through (x, y) = (30, 40) cm.

3. Replace the 250-lb force in Figure P3.64 by an equipollent system consisting of a force at Q and a couple. Then show that both systems have the same moment about point B.

Implement a single-arg constructor : Implement a single-arg constructor that sets the initial capacity of the array, with a default of 10, which also serves as the default (no-arg) constructor. The size of the array, unless it is created from an existing array, is initialized to 0.

What is the magnitude of the force exerted on the block : The acceleration of gravity is 9.8 m/s2. If Fl = 16 N and Fr = 6N, what is the magnitude of the force exerted on the block with mass 8 kg by the block with mass 5 kg?

The molarity of pcl5 but asks for atm : A lot of trouble with this question, I think because it gives you the molarity of PCl5 but asks for atm at the end and I'm not really sure how to solve the question that way. I first found deltaG standard to be 2.75 kJ, then plugged that in to find t..
