1. A crossed flat belt configuration ca n transmit more power than an open flat belt configuration
2. A ‘V’ belt has greater power transmission ca p a city than a n open belt
3. Power transmission is greater when belt tension is higher due to centrifugal effects than the s a me belt drive when centrifugal affects are absent
4. Power transmission is the greatest just before the point of slipping is reached
Power transmission is greater when belt tension is higher due to centrifugal effects than the s a me belt drive when centrifugal affects are absent
1. The smaller the shaded area , the better the material damping
2. The larger the shaded area , the better the material damping
3. Material damping is a n independent material property and does not depend on this curve
4. None of the above
The smaller the shaded area , the better the material damping
