You have to decide between two projects. project a has an initial cost of $5,000 and a useful life of 5 years, at which time it can be replace for $5,000. it has a net annual benefit of $2,500. project b has an initial cost of $9,000, a useful life of 10 years, and a net annual benefit of $3,300. which project should you select if you compare costs over a 10-year period? why would you select this project? assume marr = 30%.

What precautions should you take to prevent injuries when dealing with heavy loads?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
