Find the minimum linear thickness of liner for a 4-stroke single-cylinder water-cooled vertical diesel engine from the given data: bore diameter is 140 mm, design stress is 55 MPa, and maximum gas pressure is 3.173 MPa.
Solution:
A mild steel rod supports a tensile load of 50 kN. If the stress in the rod is limited to 100 MPa, find the size of the rod when the cross-section is rectangular with width = 3 × thickness.
Solution:
Consider the following statements about why shafts are made of steel and their alloys:
- The shaft is subjected to normal stress.
- The shaft stress alternates with respect to time.
- The shaft is subjected to pure compressive stress.
- The shaft is subjected to stress of constant intensity.
Which of these statements are correct?
Solution:
Two plates are connected with a riveted joint. A tensile force P acts on the plates such that the stress developed on the rivets is normal stress. Consider the rivet pitch to be 2 mm and the diameter of the rivet hole to be 19 mm. The allowable tensile strength of the plate material is 350 MPa, and the thickness of the plate is 5 mm. Find the maximum permissible value of P for the joint not to fail.
