@Baluncore I came at this from a slightly different angle, using the following calculator to get started (https://www.engineersedge.com/calculators/torque_calc.htm): Arm/Lever torque around pivot point: 18 (kg) x 0.17 (mm) x 9.81 (m/s2) = 30 Nm Bolt Clamp force: Bolt torque 5 (Nm) / Bolt...

Understood. Lets assume the inner diameter is 12 mm and the outer is 40. How do we calculate the force in the case of flat 'brake pads' on the arm? And then what changes in the calculation when you go to a conical bake pad like shown below? I know that this set up will give a better braking...

Thanks for the feedback. Does the below illustration help?

Hi guys, I am trying to design a brake/locking mechanism to hold up a weight, here is some background; I have a weight 18kg, 170mm away from the pivot point on an arm. A brake compresses the arm at the pivot point. This consist of a M10 bolt compressing a surface area of 1500mm^2 on each side of...
