when 10 cm rope pull axle and wheel and in which axle is 10 cm in diameter and wheel is 100 cm in diameter in which wheel hangs a weight 10 kg of metal ..in this how to much torque is required to rotate axle?
siva surya said:in this
1.how much torque is reuired to rotate axle of diameter 10 cm
2.and on the other end wheel is attached of diameter 100 cm and hang with 10 kg of weight
3.then in how many kg should be axle and wheel metal ?

how much torque is required to pull up to weight 11 kg from 100 cm through wheel and axle?CWatters said:The impact force depends on what the 10kg mass is made of and what it hits. One way to visualise this is that it will be higher for concrete than carpet because the "stopping distance" is shorter.
If you assume it hits something like modelling clay and has constant deceleration you can estimate using..
V2 = U2 +2as
where
U2 = velocity at impact
V2 = velocity after impact, probably zero
a = acceleration
s = distance (eg depth of impact crater)
So you could measure the depth of the impact crater and plug in the numbers to estimate the deceleration "a".
Then use F = ma to estimate the implied impact force.
The results will be very approximate. In the real world it's better to attach an accelerometer to the mass and measure "a".

CWatters said:The torque must be at least..
= (10Kg * 9.81) * 100/10
= 981 Nm
To calculate torque, you will need to know the radius of the axle and the wheel, as well as the force applied to the wheel. The formula for torque is torque = force x radius. In this case, you will need to convert the radius of the axle to meters, as the formula requires units of meters. So, if the radius of the axle is 10 cm, it would be converted to 0.1 meters. Then, you can plug in the values and solve for torque.
Torque is typically measured in units of Newton-meters (N*m) in the metric system or foot-pounds (ft-lb) in the imperial system.
The length of the axle and wheel can affect the amount of torque required to turn the wheel. The longer the axle and wheel, the more torque is needed to overcome the resistance and rotate the wheel. This is because the longer the distance from the center of rotation, the greater the lever arm and the more torque is needed to produce the same amount of rotation.
Yes, torque can be negative. Negative torque, also known as "reverse torque," occurs when the direction of rotation is opposite to the direction of the applied force. This can happen in situations where the force is trying to slow down or stop the rotation of the wheel.
Torque and power are related, but they are not the same. Torque is the measure of rotational force, while power is the rate at which work is done. The relationship between torque and power is described by the equation power = torque x angular velocity. This means that a higher torque can result in a higher power output, but it also depends on the speed at which the torque is being applied.
