You are in charge of a large assembly shop. One of your customers has promised to award you a large contract for the assembly of 1000 units of a new product. The suggested bid price is based on an average of 20 hours of direct labor per unit. You conduct a couple test assemblies and find that, the first unit took 50 hours and the second unit completed in just 45 hours. How many hours do you expect the assembly of the first hundred units and the second 100 units to take? Is the contractor’s assumption about the average labor hours per unit valid or should the price be revised?

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
