If the speed of the material just before it strikes the plate is equal to the speed of the material just after it strikes the plate, determine an equation for the mass flow rate of the material, based on the horizontal force readout on the sensor. The truth is that most professionals have heard all types of questions, so ask whatever you want. Even though energy is conserved for the system, why is it a good idea to make the components of the drive mechanism as light as possible with the exception of the flywheel? You will likely have to take some time to work through them. It uses large parabolic mirrors to focus sunlight onto a central receiver, which powers a Stirling engine. You can also the site for previous answers. Its acceleration is given by where C is a constant, n is a real number, and t is time.

To see how I select questions to answer,. You get 1024 characters of space to ask a question. In this process, a punch pushes an aluminum billet of diameter D through a die of smaller diameter d. To correct this imbalance it is recommended to cut out a groove around the outer circumference of the impeller, using a milling machine, on the same side as the imbalance. Therefore, θ can be differentiated with respect to time. Using a geometric argument no equations , determine the location of the nodes. Determine the path traced by the end point P as the blue linkage of length b rotates back and forth.
