For the given Assertion (A) and Reason (R), choose the correct option.
Assertion (A): Considering the velocity ratio and center distance to be same, V-belt
is capable of transmitting more power than flat belts for similar materials (and
having same maximum permissible tension).
Reason (R): The wedge action in flat belt permits smaller arc of contact that results
in increasing the pulling capacity of the belt.
Answers
Answer:
Contrary to this, in crossed belt drive, belt proceeds from the top of one pulley to the bottom of other pulley and thus crosses itself in between two pulleys. Here driving shaft and driven shaft rotate in opposite directions. It offers higher contact angle, so power or torque transmission capacity also increases.
Answer:
Explanation:
Definition of velocity:
The primary indicator of an object's position and speed is its velocity. It is the distance that an object travels in one unit of time. The displacement of the item in one unit of time is the definition of velocity.
Definition of distance:
Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.
Definition of capacity:
the capacity to control or handle something There are many seats available in the space. Factory capacity is being reached. aptitude or strength You are capable of doing better. volume perception 3 Ten gallons can fit in the tank.
