In a machining operation that approximates orthogonal cutting, the cutting tool has a rake angle 8°. the chip thickness before the cut to= 0.15 mm and the chip thickness after the cut tc=0.3375 mm. calculate: a) the shear plane angle and the shear strain in the operation b) the shear strength of the work material assuming the cutting and thrust force were measured to be fc = 679.5 n and ft=535.5n. the width of the orthogonal cutting operation is w= 2.5 mm. c) the friction and the coefficient angle d) the cutting power and specific energy in the machining if the cutting speed 60 mm/min

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.
