Design a quick return 4 bar linkage whose input is driven by a constant speed motor and whose output oscillates between 52 degrees and 110 degrees with the clockwise motion time being 1.25 times slower than the counter clockwise motion. The ground pivot point (O2 and O4) should not be further than 12 inches apart. a. Calculate the angles needed to achieve this time ratio (1 pt) b. Show the sketch of the graphical construction used to synthesize the, with important angles indicated. (4 pts) c. Draw the final four bar linkage to scale (3 pts) d. List the lengths of all the links (1 pts) e. What is the angle of the GND link measured counter clockwise with respect to the horizontal (1 pts) f. Identify the class and inversion type of your mechanism (1 pts) g. Extra credit: Simulate the linkage in Creo Mechanism to

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
