1.	A strip cantilever gets depressed by 3 mm due to some load. Find the depression will be produced in another cantilever with length and breath double those of the first?
Answer» Solution :DEPRESSION produced in cantilever `delta=(4WI^(3))/(YBD^(3)) :. Delta alpha(I^(3))/(B) :. (delta_(2))/(delta_(1))=((I_(2))/(I_(1)))^(3)((b_(1))/(b_(2)))=2^(3)xx(1)/(2)=4 :. delta=4xx12 MM`
