Find the load that will compress the cast iron bar a total of 1 mm in the length of 1m. b. Find the load that will compress the steel shell a total of 1 mm in the length of 1m. c. What is the total load that will compress the combined bar a total length of 1mm.

a. Find the load that will compress the cast iron bar a total of 1 mm in the length of 1m.
b. Find the load that will compress the steel shell a total of 1 mm in the length of 1m.
c. What is the total load that will compress the combined bar a total length of 1mm.
d. Find the deformation of the cast iron bar if it has a coefficient of thermal expansion of 10.8 μm/(m°C), and if there’s a decrease in temperature by 25°C.
e. Find the deformation of the steel shell if it has a coefficient of thermal expansion of 11.7 μm/(m°C), and if there’s a decrease in temperature by 25°C.
