Question

What pressure should be applied to a lead block to

reduce its volume by 10% ? ​

Answer 1

Alright!

We were told that the compression is ten percent. Or, in other words.

1−V2V1=.1

V2V1=.9

Assuming that bulk modulus is constant.

ΔP=−KlnV2V1

K=ΔPlnV1V2

Alternatively, the engineering strain could be used instead of true strain, which would just be…

K=ΔP1−V2V1

There you go
