Garage Shutter Opening and Closing Using PLC
If the size of the gate is 9feet*9feet and it has to be opened in exact 12 sec, and diameter of the shaft used is 3cm. Calculate the speed of rotation of the shaft.
_______ is a kind of switch, which is ________ or ________ the moment we press or depress it.
Limit switches are commonly used for
___________ is a device, that uses __________ and __________ to provide speed and torque conversions from a rotating power source to another device.
If the mass of the garage shutter is 500kg, and the diameter of the shaft used to pull is 9.6cm. Calculate the torque required to pull the garage shutter? Assume g=10m/s2.
A proximity switch can be
If the size of the gate is 12feet*12feet and it has to be opened in exact 10 sec, and diameter of the shaft used is 2.4cm. Calculate the speed of rotation of the shaft.
If the diameter of the shaft used to pull the garage shutter is 2.4cm and the size of the garage shutter is 12feet*12 feet, rotation of the shaft is 500rpm. Then calculate the time required by the garage shutter to open completely from its completely closed condition.
If the mass of the garage shutter is 300kg, and the diameter of the shaft used to pull is 2.4cm. Calculate the torque required to pull the garage shutter? Assume g=10m/s2
The above figure represents a micro switch (limit switch), it has one normally open connection (N.O) and one normally closed connection (N.C). The connection between terminal1 and terminal2 is ________ and connection between terminal1 and terminal3 is _________.
If the diameter of the shaft used to pull the garage shutter is 9.6cm and the size of the garage shutter is 15feet*12 feet, rotation of the shaft is 1000rpm. Then calculate the time required by the garage shutter to open completely from its completely closed condition.
If the motor used for garage shutter opening and closing produces a torque of 7N-m and the torque required to pull the garage shutter is 14N-m.Calculate the required gear ratio.
