    Max Force on a single rototiller blade

    I am think I am just confusing myself. So if I have 180 rpm and 60 Hp, I have a torque value of T=1750 lb-ft. Is this the max amount of force I will see at the end of the blade if it were to hit a rock (disregard the shear bolt)? Or is there a shock force/ impact force that will be greater? If...

    Max Force on a single rototiller blade

    The shear bolt will be rated at 60 hp. I just cannot remember how to so solve for when the blade stops abruptly. Finding the angular moment of inertia I just use L=Iw. After that what equation do I use to solve for the abrupt stop.

    Max Force on a single rototiller blade

    Jack action, the final design will have a slip clutch or shear bolt in line to be the "weak spot" i just was wanting to know my limits.

    Max Force on a single rototiller blade

    I am looking to see if the blade will brake off if the tiller hit a rock and how big the bolts need to be that hold the blade in place. This will also give me an idea on how much force will be applied to the shaft

    Max Force on a single rototiller blade

    I am looking to find the max force on a single rototiller blade. The blade is being rotated at 180 RPM with 60Hp. The blade is bolted to a Flange that is welded to center shaft. The shaft has a 3.5" diameter. The diameter of the cutting circle is 24". The blade is a 10.25"x3"x.25" rectangle. If...
