Draw a fourbar linkage with L1 = 10 cm, L2 = 3 cm L3 = 6 cm and L4 = 6 cm, with LaTeX: \theta_2θ 2= 45o. Consider both configurations in your drawing, namely the open and closed. Measure your transmission angles and indicate which is which. Do you see a difference in values? (0.25 point - lengths measurements)
(0.5 point - angles measurements)
(0.5 point - both configurations)
(0.5 point - neatness)
(0.5 points – links dwg)
(0.25 points - transmission angles measurements)

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.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
