1. ### Motion of a body - conveyor/catapult/trebuchet design

Hello All, I posted this same question to the classical physics forum - but I'm reckoning it's more ideally suited for a Mechanical Engineer: I'm currently working through a scenario in which the following occurs: An object of mass M1 (kg) approaches a rotating wheel at a speed of S1...
2. ### Projectile Trajectory - as influenced by multiple factors

Hello All, I'm currently working through a scenario in which the following occurs : An object of mass M1 (kg) approaches a rotating wheel at a speed of S1 (m/s) along a belt The belt is at an angle Th1 (degrees) to the horizontal axis The rotating wheel has a linear velocity equal to S1...
3. ### Calculating maximum load on a thread

Can any one offer a method or location of a method for determining the permissible axial load that can be applied to an internal thread? i.e. Take a nut and screw into it two bolts, one from either end so they meet in the middle of the nut, then apply a tension force across the two bolts. How...
4. ### Internal thread tensile strength

calculation of internal thread tensile strength Hi All! I've got a coupling device that has two internal threads of different pitch, length, diameter. The smaller thread takes a lifting bolt, the larger attaches to a piece of machinery. I've been asked to work out the safe working load (SWL)...
