Like what Aerodium hasAnd where could you get it cheap?
There are many plans available for building your own rotor, if this is for a wind millThere are templates available that you can cut a propeller from a 10-14 ft edge grained board (edge grain doesn't warp much) I also have seen propellers made out of aluminum tubes with a sail cloth used for the chord width and the aluminum tube being the leading edgeA cable is used for the trailing edge Just Google homemade windmill plans, where you can either buy parts already made or make your own
First find the acceleration utilizing Fma F210N mforty five+3075kg a F/m 210/75 42/15 14/5Now we know the acceleration of every block is 14/5m/s^2 anticipate the 45kg block is hooked up to the 30kg block which is hooked up to the forceConsidering that the 45kg block has a 14/5m/s^2Then it need to have a F maforty five14/5126N If i have the blocks reversed the F ma 3014/5 84N The drive pulling the block is the anxiety in the rope.
The weight acts down (gravity), so the tension must act up to balance weightBeing vertical, the rope tension will be greater at the top end than the load end, as the rope has massTheoretically if that rope were to snap due to overload, it would snap at the top.
Tension always acts on a mass that is attached to the cable/rope/stringThe direction of the tension force is always in the direction that the cable is oriented, relative to the massFor example, if the cable stretches away vertically from the top of the mass, then the direction of the tension force (on that mass) is vertically upwardBasically, you can draw a force vector, starting from the mass, and pointing in the direction that the rope is oriented, and that represents the tension force vectorNotice that if a single rope is connected to more than one mass, it may exert a tension force in more than one directionFor example, if the rope goes around a pulley attached to a table, one end of the rope may exert a horizontal tension force on one mass, while the other end exerts a vertical tension force on another massThat's perfectly OKWhen analyzing the tension force on a given mass, just look at the direction of the rope where it's attached to THAT mass.
