1. Find the magnitude of two like parallel forces acting at a distance of 240 mm, whose resultant is 200 N, and its line of action is at a distance of 60 mm from one of the forces.?
2. ABCD is rectangle, in which AB = CD = 100 mm and BC = DA = 80 mm. Forces of 100 N each act along AB and CD and forces of 50 N each at along BC and DA. Find the resultant moment of the two couples.?
3. Two men carry a weight of 2 kN by means of two ropes fixed to the weight. One rope is inclined at 45° and the other at 30° with their vertices. Find the tension in each rope.

A 1.00 M solution of Cu(NO3)2 is placed in a beaker with a strip of Cu metal. A 1.00 M solution

of SnSO4 is placed in a second beaker with a strip of Sn metal. A salt bridge connects the two

beakers, and wires to a voltmeter link the two metal electrodes.
