(i) To move a boat uniformly along the river at a given speed, a resultant force R = 520 N is required. Two men pull with force P and Q, by means of ropes to do this. The ropes make an angle of 30° and 40° respectively with the sides of the river as shown in Fig. 1. (i) Determine the force P and Q, (ii) If 01 = 30° , find the value of 02 such that the force in the rope Q is minimum. What is the minimum force Q ? 300 R 02 400

Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?

1. Do a project research based on this topic. Gas turbines are used for many purposes from aeroplane engines to industrial electric power generating sets. They are at the heart of most jet engines but also for propeller driven engines. Hence, do a mechanical report on operation for gas turbine plant and justify its operation.
