Why is the angle of contact (lap) at the smaller pulley taken into consideration while using the belt tension equation T1/T2 = eμθ?
- 1The power transmitted depends only on the diameter of the smaller pulley.
- 2Belt slipping occurs first on the smaller pulley due to its smaller angle of lap.✓
- 3The smaller pulley is always configured as the driving pulley.
- 4The smaller pulley is weaker compared to the larger pulley.
Correct answer
Belt slipping occurs first on the smaller pulley due to its smaller angle of lap.
