List of top Mechanical Engineering Questions on Machine Design asked in AP PGECET

Which type of bearing is best suited for high-speed applications with moderate radial loads?
A shaft is required to transmit a power of 25 kW at 360 rpm. The force analysis due to attached parts results in Bending Moment of 830 Nm at a section between bearings. If permissible stresses in the shaft are 60 N/mm\(^2\) in bending and 40 N/mm\(^2\) in shear, calculate the diameter of the shaft.
What is the primary reason for using a key in shaft and gear assemblies?
The two plates are welded by a butt joint and is subjected to tensile force P as shown in figure. The average tensile stress in the weld is
Which theory is commonly used to predict the failure of ductile materials under multiaxial stress states?
The criterion of static load carrying capacity is the permanent deformation of the parts of bearing. The limiting value of permanent deformation is
Angle of twist of a shaft of diameter 'd' is inversely proportional to
