what is the difference between solid and rigid (in physics)

for example, a rigid object ..a solid object

rigid means it won't deform.

 

solids however can deform.

 

exampes of deformable solids, rubber tyres, paperclips bending, silly putty, plastic bottles, spring, elastic bands, etc.

 

these are all solid, but not rigid.

And a hollow metal shell is rigid but not solid.

elasticmodulus = stress/strain

 

is it true?

elasticmodulus = stress/strain

 

is it true?

 

Yes, have a look at the Wikipedia article.
