Hey frnds plzz suggest if u have proper idea how to approach .... i found some topic weak in all subjects kindly where it is best to read in order to improve myself... SOM.. STRUCTURE BASED QUS LIKE c shape beam and at the end point load so calculate all forces in each joint,deflection problem by strain energy method and thick cylinder
Tom... vibration and balancing specially dynamic radial engine balancing I
ndustrial... inventory for practicing good qus,ppc theory
Md.. brake qus basically involve energy conversion like after braking how much time needed to stop wheel.. Production..MILLING,deep drawing shaper planer ,BLUbased,EDM AND other machining based qus solun and practicing both
Fluid machinery.. cavitation,npsh based qus and theory
Mechanics... basic energy conversion process and more GATE oriented Maths.. matrix theory qus
Aptitude and english..to optimize more in GATE guide..
A uniform circular ring of mass M and radius r is rotating with an angular speed w about an axis passing through its center and perpendicular to the plane of the ring. Two identical beads, each of mass m, somehow get attached at two diametrically opposite points. The rotational speed of the ring will become
One-half length of 50mm diameter steel rod is solid while the remaining half is hollow having a bore of 5 mm. The rod is subjected to equal and opposite torque at its ends. If the maximum shear stress in solid portion is t , the maximum shcar stress in the , hollow portion is:
