a power-shift crawler tractor is excavating tough clay and pushing it a distance of 95 ft maximum reverse speeds are: first range, 3 mi/h (4.8 km/h); second anee, smi/h (8.1 km/h); and third range, 8 mi/h (12.9 km/h). Rated blade capacity 1S a\ 10 LCY (7.65 LCM). Estimate dozer production if the job efficiency factor is 0.83

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.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
