Explain the term: Moment of Inertia and polar moment of inertia. Derive expression for polar moment of inertia of a rectangle using principle of integration.
Design a cotter joint to connect two steel rods of equal diameter. Each rod is subjected to an axial tensile fore of 50 kN. The cotter is made of steel 30C8 (Syt = 400 N/mm²) and factor of safety is 6.
Derive an expression for bending stress in straight beam subjected to bending moment.
A rectangle beam 300 mm deep is simply supported over span of 4 m. What uniformly distributed load the beam may carry if the bending stress is not to exceed 120 MPa ? Take I = 8 Χ 10⁶ mm4 .
Define torsional rigidity. Derive equation for angular deflection of shaft subjected to twisting moment.
A machine component is subjected to fluctuating stress that varies from 40 to 100 N/mm² . The corrected endurance limit stress is 270 N/mm² . The ultimate tensile strength and yield strength of the material are 600 and 450 N/mm² respectively. Find factor of safety using
A rigid flange coupling is used to transmit 20 kW power at 720 rpm. There are four bolts and pitch circle diameter of bolts is 125 mm. The bolts are made of steel 45C8 (Syt = 38 N/mm² ) and the factor of safety is 3. Determine the diameter of bolts. Assume that the bolts are finger tight in reamed and ground holes.
Explain stress concentration. Explain the causes of stress concentration and discuss remedies for reduce it.
A two start, trapezoidal screw is used in screw jack to raise a load of 300 kN. The screw has nominal diameter as 100 mm, pitch as 12 mm and half thread angle is 15° . Coefficient of friction in screw threads is 0.15. Neglecting collar friction, calculate :
What is " overhauling" of power screw. Discuss the condition for overhauling and its application.
In a machine vice, a screw with single start square threads with 22 mm nominal diameter and 5 mm pitch is used. A friction collar provided in the body has inner and outer diameter as 45 mm and 55 mm respectively. The coefficient of friction for both the thread and collar is 0.15. The operator can apply 100 N force on handle which is 150 mm long. Assuming uniform wear for collar, Calculate
