Design a joint to fasten together two pieces of 1045 sheet steel, each 4 mm thick and 6 cm wide, which are lapped over each other and loaded with 100 N.

Consider the following two statements:

 

• What size SAE grade 5 bolt should be used to fasten together two pieces of

1045 sheet steel, each 4 mm thick and 6 cm wide, which are lapped over each

other and loaded with 100 N?

• Design a joint to fasten together two pieces of 1045 sheet steel, each 4 mm

thick and 6 cm wide, which are lapped over each other and loaded with 100 N.

(a) Explain the difference between the two statements.

(b) Change a problem from one of your engineering science/physics classes

into a design problem.
