A ball is dropped from a height .If it takes0.200 second to cross the last 6.00 m before hitting the ground ,find the height from which it was dropped .
Ans) We need to find HUsing second eqn of motion:6=0.2u-5(0.04).............................u is velocity at h=6mu=31m/sConserving energy:mgh=0.5m(31)2.......................................Datum line for P.E is at 6 m from ground. h= H-6=>h=48.05m=>H=54.05m.
Fixed Support: At such support beam end is not free to translate or rotate at the fixed end there are three reaction horizontal reaction ( R H ), a vertical reaction ( R V ), an

a) Round off the numbers 865250 amd 37.46235 to four significant figures and compute Ea, Er, Ep in each case. b) IF u= 4 x 2 y 3 /z 4 and errors in x, y, z be 0.001, determine

a) A carbide tool with mild steel work piece was found to give life of 2hours while cutting at 50 mpm. Calculate the tool life if the same tool is used at a speed 25% higher than p
the movability of 3 bar mechanism is zero then how can we comment on instantaneous centre of it?
Advantage of Electro Chemical Machining 1. As the tool does not come in contact with the work there for tool wear is practically nil. 2. The metal removal is faster rate.
