If the angle of wrap on smaller pulley of diameter 250 mm is 1200 and diameter of larger pulley is twice the diameter of smaller pulley, then the centre distance between the pulleys for an open belt drive is
In case of CVT, if the drive pulley diameter is decreased and the driven pulley diameter is increased, output torque will be increased and output speed will be decreased.
The layout of a shaft supported on bearings at A & B is shown. Power is supplied by means of a vertical belt on pulley B which is then transmitted to pulley C carrying a horizontal belt. The angle of wrap is 180’ and coefficient of friction is 0.3. Maximum permissible tension in the rope is 3kN. The radius of pulley at B & C is 300mm and 150mm. Calculate the tension in the rope of pulley C.

If the velocity ratio for an open belt drive is 8 and the speed of driving pulley is 800 r.p.m, then considering an elastic creep of 2% the speed of the driven pulley is
A main shaft is running at 250 rpm and machine spindle is to be driven directly from the main shaft to tum at 25 rpm. If the diameter of pulley fitted on machine spindle is 20 em, what would be the diameter of pulley fitted on main shaft?
The layout of a shaft supported on bearings at A & B is shown. Power is supplied by means of a vertical belt on pulley B which is then transmitted to pulley C carrying a horizontal belt. The angle of wrap is 180’ and coefficient of friction is 0.3. Maximum permissible tension in the rope is 3kN. The radius of pulley at B & C is 300mm and 150mm. If allowable shear stress in the shaft is 70N/mm² and torsional and bending moments are M=1185000N-mm and m=330000N-mm, find the diameter of the shaft.
Study the following information to answer the questions given below: A company visited an Engineering college for placement drive where students of any branch can participate in the drive. But company put some eligibility criteria. 1) Student having no backlogs are eligible to participate in the drive. 2) Student having greater than 9.8 CGPA without any backlogs are eligible for direct interview round. 3) Student must have at least 70 percentage in 10th and 12th. If the 1st and 2nd criteria not fulfilled then, a) If student has 1 or 2 backlog and the result is awaiting but having a CGPA 8.5 then he has to participate in presentation round before the interview round. Sameer a Mechanical student is the topper of the college having 90 percentage in both 10th and 12th. But he is having a 1 backlog in his 4th semester and the result is awaiting. His CGPA is 8.8.
