An aluminum cylinder bar ( 70 GPa E m = ) is instrumented with strain gauges and is subject to a tensile force of 5 kN. The diam
eter of the bar is 10 cm. The Poisson’s ratio of the bar is 0.33. A Wheatstone bridge is constructed to measure the axial strain. Gauge 1 measures the axial strain and gauge 2 measures the lateral strain.

Answer:
47.91 sec
Explanation:
it is given that
at t=0 velocity =0 ( as it is given that it is starting from rest )
we have to find time at which velocity will be 3.3
we know that
integrating both side
---------------eqn 1
at t=o it is given that v=0 putting these value in eqn 1 c=0
so
when v= 3.3
t=
=47.91 sec
Answer:
M =2.33 kg
Explanation:
