An incentive plan employing a kicker is in use. below standard performance the worker is guaranteed a rate of $6 per hour and above standard performance the worker is paid $9.20 per hour.

a job is studied and a rate of 0.036 hours per piece is set.

what is the direct labor cost per piece at the following efficiencies:
a. 50 percent?
b. 80 percent?
c. 98 percent?
d. 105 percent?
e. 150 percent?

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.
