one of the following is not related to V-belt drive types :
Classic V‐Belt
Narrow V‐Belt
Cogged V‐Belt
Angular V-Belt
Narrow V‐Belt can handle twice the load of a classic v‐belt of the same width ( T or F )
(a)
Classic V‐Belt can handle light to heavy loads based on its belt Length ( T or F )
(a)
the V-belt which improved flexibility for better performance, reduce slippage, and increases motor speed and efficiency :
Classic V‐Belt
Narrow V‐Belt
Cogged V‐Belt
Angular V-Belt
Metric v‐belt sizes are designated by pitch length and cross‐section ( T or F )
(a)
V-belt cross section is indicated by three‐letter code and its
(a) for a light‐duty belt
V-belt cross section is indicated by three‐letter code and its
(a) for heavy‐duty applications
