I have torque max and min on an output shaft without any load but need to calculate the maximum under load in order to choose correct shaft diameter, how do i go about this? Alternatively, should i just include a higher factor of safety? Thanks

Engineering isn't a natural talent and it's only fundamentally about maths and physics, there are a world of possibilites within. I doubt you aren't cut out for it, I'm a second year student and I'm by no means natural, i just work hard.

I am struggling to understand whether a jigsaw blade which should be operated perpendicularly to the cutting surface needs to resist shear force? Anything obvious i have missed would be appreciated! Thanks

I must plead "noob" on this subject if I'm honest, i mean yes there is gearing but i don't have the ratio's, this is the exploded view of the saw i am analysing. http://www.makitauk.com/shop/parts/partdrawings.asp?groupid=2125&model=BJR181RFE3&fromItemInfo=1

I know power = Torque x angular velocity (rad/s) AND I am wondering if angular velocity can be calculated through strokes per minute? The product is a reciprocating saw (not orbital). In this case are RPM's the same as SPM'S? Thanks
