i need to know how to calculate the torque needed to apply through my hand to hold a certain hand drill in place while drilling in concrete wall so that the hand drill willl rotate the bit instead of my hand.
i just need to know the general equation for a torque i need to apply, i think if we assume that the force from the concrete wall is 10 Newtons i would have to apply more than 10 Newtons right?BvU said:I suppose you do. What are the parameters and relationships you have at your disposal to do this calculation ? Wouldn't it be easier to determine what you want to know experimentally ?
You can estimate it using nomimal power of the drill as the maximum torque you need to hold the machine. Remember P= T x w the speed i suppose is known.ahmed11 said:i need to know how to calculate the torque needed to apply through my hand to hold a certain hand drill in place while drilling in concrete wall so that the hand drill willl rotate the bit instead of my hand.
A torque is more than just a force. It involves a force and an offset between the point of application of the force and the axis of rotation. The longer the handle on a wrench, the less force you need to budge a stuck nut. Accordingly, the appropriate units for a torque involve a force times a distance. For instance, a Newton-meter or a pound-foot.ahmed11 said:i just need to know the general equation for a torque i need to apply, i think if we assume that the force from the concrete wall is 10 Newtons i would have to apply more than 10 Newtons right?
it's the difference in forces that gives this relation right?
if i put 9 Newtons from my hand and 10 Newtons is coming out of the wall then my drill and hand will rotate with force of -1 Newtons which is the opposite direction i think??
would appreciate your help
Torque is a measure of the force that can cause an object to rotate around an axis.
In drilling, torque is the force that is applied to the drill bit to rotate it and create a hole in the material being drilled.
The equation for calculating torque for drilling is: Torque = Force x Distance. In this case, the force is the pressure being applied to the drill, and the distance is the length of the drill bit.
The torque needed for drilling can be affected by factors such as the type and hardness of the material being drilled, the size and type of drill bit, and the speed and pressure of the drill.
Calculating torque for drilling is important because it helps determine the amount of force needed to successfully drill through a material. Too little torque may result in an ineffective drill, while too much torque can cause damage to the drill bit or the material being drilled.
