A CNC milling machine has a purchase price of £120,000 and it is considered from an accounting standpoint to be depreciated to zero value over a period of 5 years. If the machine is to be used for 2 shifts with each shift working for 37 hours/ week and 45 weeks/ year. What is the machine cost/ hr which must be charged in order to amortise/repay the costs over the 5 year period? To make the calculation simpler, you can assume that over the 5 year period you will be required to pay back 8% interest on the sum borrowed. Express your answer in § / hour rounded up to the nearest penny

The pulley below has a mechanical advantage of 3 and has a load of 300N assume an ideal pulley without friction losses, determine the following: a) what input force (input) do you apply to lift the load of 300 N? B) what is the tension in the 3 lines of the ropes of the pulley on the output side with the load as illustrated in the diagram? C) if the load is lifted to a height of 12 cm, how much rope is pulled on the input side d (in) in the diagram? D) how much work in joules (j) is required to lift the 300 N load 12 cm (0.12m)? E) how much power in watts (w) is required to lift the 300N load a distance of 0.12m in 20 seconds.

In a factory, the direct cost is also called variable cost because: O It is connected with the production It is changed according to the supply and demand O All of the choices O None of the choices O It is connected with fixed cost
