Hi,
The force that the arms would exert is equal to to the torque of the motor divided by the distance from the motor to the point of contact (F=T/d)
Depending on the angle (anything that isn't verticle), the torque would be effected by gravity. For example if the robot weighed 10kg and...
Hi,
You need a pressure of 9.5psi to keep the valve shut (difference in pressure). Using F = P*A and W = F/g I get a weight of around 1075lbs. Seems a lot but it's quite a straight forward calculation - you have a large area that the pressure is acting on.
Hi,
The following equation might help.
q = 2 π k (ti - to) / ln(ro / ri) (1)
where
q = heat transferred per unit time per unit length of cylinder or pipe (W/m, Btu/hr ft)
k = thermal conductivity of the material (W/m.K or W/m oC, Btu/(hr oF ft2/ft))
to = temperature outside pipe or...
Hi there,
I'm trying to find a solution to a problem that I thought was straight forward, but am now struggling with.
I've got a shaft with a fixed end set up, where there is a small diameter fixed and then it steps up to a larger diameter which is having a torque applied to it.
I'm...
