GATE Mechanical 2014 Set 1 | Question: 51
A metal rod of initial length $L_0$ is subjected to a drawing process. The length of the rod at any instant is given by the expression, $L(t)=L_0(1+t^2)$ , where $t$ is the time in minutes. The true strain rate (in $min^{−1}$) at the end of one minute is _______

GATE ME 2013 | Question: 38
During the electrochemical machining $(ECM)$ of iron (atomic weight $= 56$, valency $= 2$) at current of $1000$ $A$ with $90\%$ current efficiency, the material removal rate was observed to be $0.26 gm/s$. If Titanium (atomic weight $= 48$, valency $= 3$) ... with $90\%$ current efficiency, the expected material removal rate in $gm/s$ will be $0.11$ $0.23$ $0.30$ $0.52$

GATE ME 2013 | Question: 35
In a $CAD$ package, mirror image of a $2D$ point $P(5,10)$ is to be obtained about a line which passes through the origin and makes an angle of $45^{\circ}$ counterclockwise with the $X$-axis. The coordinates of the transformed point will be $(7.5, 5)$ $(10, 5)$ $(7.5, -5)$ $(10, -5)$
