Can someone please help me with this Physics problem?
This is not for any credit. Im having trouble can someone please help me?
Elasticity problem: A steel piano wire 2.45 m long, with a cross sectional area of 0.19 mm^2, has a mass of 5.9 kg suspended at one end. How much does the wire stretch? Young’s modulus for steel is 2.0 x 10^11 Nm^-2.
Please help me, I’m having trouble with this.
young modulus=stress/strain
where stress=force/area
and, strain=change in length /original length
F=w (since it is suspended)= mg=5.6*9.8=54.88N
area= 0.19 mm^2= 0.19 /1000000 m^2= 1.9*10^-7
Young mod=2 * 10^11
original length=2.45m
