Propeller Design Analysis

First, I want www addresses on online engineering forums which they will answer-solve related engineering problems,quickly and accurately.

Second, " A propeller for a lightwave speedboat capable for been used in inland waters or at sea is currently made out of brass (a copper alloy).In service, the blades are deflecting too much a high rotational speeds i.e(it is not stiff enough).Use a chart of Young's modulus (stiffness) against density to choose three alternative metals which are stiffer, but which will not lead to a heavier component, i.e(they are not greater in density than brass).If possible mention briefly the relative advantages and disadvantages of the alternatives, bearing in mind the service conditions.

Please if you can't help me on the appropriate problem give me www addresses for engineering forums which they can help me on similar problems (on-line).
