Company Y is considering a new widget investment. If they pursue the investment, it will cost $200,000 today. It has an expected life of 10 years and no salvage value. Annual expenses are estimated to be $35,000 per year. Annual revenue increases are estimated to be $70,000 per year. Company Y must borrow 1/4 of the purchase price. The bank has agreed to five equal annual payments, with the first payment due at the end of year 1. Company Y's MARR is 15% compounded annually. The loan interest rate is 10% compounded annually. a) How much is the loan payment? b) What is the present worth of this widget investment opportunity? c) Based on the present worth analysis, should Company Y make the investment? Why or why not? [Create an xls file to solve OR capture an image of your \"by hand\" work and upload here) Upload Choose a File

10. Pulley A is connected via a belt to a motor (not shown), which creates the in- dicated tensions. The motor causes the assembly to rotate at 500 rpm. The resulting power is delivered via the shaft to pulley B, creating tensions, $T_2$ and $T_1$, which work on some load (not shown). Both pulleys are fixed to the shaft. You may assume perfect bearings at O and C. (a) Assuming steady-state operation, find the power delivered through this pulley- shaft-pulley assembly. Hint: Find the net torque on pulley A. Then use the formula $Pow = T\omega$, being very careful with units (all dimensions are in mm). (b) Find the magnitudes of the tensions, $T_2$ and $T_1$. You may assume that the slack-side tension is 10% of the tight-side tension. Is it very clear to you which is larger?
