I have two wind turbines that I am trying to wire up for power generation. They are three phase wild ac. I have a charge controller setup with dump resistor but I want to know if I can take the wires and connect each of the three wires to their counter part from the other generator and then...

savonius blades have a estimated TSR of one since it is a drag device and not a lift device. We can calculate the area of the blade that will have the wind pushing against. What I need to determine is if the blades will rotate on our bearings based upon the wind speed that is hitting it.

Ok I have a design project that I am working on for the University this semester. Having a bit of problems trying to figure out and issue revolving around the wind force on our savonius blades. We are trying to make sure our blades will rotate with a wind speed of 10 mph. We have the blade total...

So I should divide right down the middle of CE and BD correct? And that the the two forces reacting at B the x force is also the force of BD, that they are one and the same.

Homework Statement The truss shown is part of an airplane’s internal structure. Determine the axial forces in members BC, BD, and BE. Homework Equations The Attempt at a Solution Ok I am trying to figure out how or where to divide this truss up and forces to draw when I do. I...

So then I just say that I set A=D(14)/4 Replace A in equation B(4)=12(D+ (D(14)/4)) Solve for D and then replace D and A values that I get into the equation for C(24)=6(B+D+A) solve for C and that is it? Please tell me that it wasn't that simple?

Homework Statement The mobile is in equilibrium. The fish B weighs 27 oz. Determine the weights of fish A, C and D. (The weights of the crossbars are negligible). Homework Equations Moment = Force*Distance The Attempt at a Solution My idea here is to use the moments about each...

So what I need to do to find the Tensions of BE and BD I need to set up the Tension times the Perpendicular distance to point A? Do I need to take the tensions and place them as if they are only in the x-z plane? I guess what I am trying to figure out is how do I need to go about to get the...

Homework Statement The tower is 70 m tall. If the tension in cable BC is 2 kN, and you want to adjust the tensions in cable BD and BE so that the couple exerted on the tower by the fixed support at A is zero. A) Determine the tensions in cable BD and BE by applying the sum of the...

Oh no Jay this is my New boss giving me a problem to figure out and then derive a formula or solution that I can put into excel so that when we get an inquiry about load points for our Isolators that we could if need be tell them which product would best suit their needs out of our product line...

Homework Statement Well this is the second time I have been given a problem that I just don't know what to do at work. Simply put you have a beam that has 3 supports. A,B,C. With a weight at point w. The goal I am told is to find all 3 points with just the the known of w (weight), L(length...

See this is what driving me batty. I know that uniform load would distribute evenly if it is at the center of gravity. Knowing that also should the center of gravity move then the weight distribution will shift. But some where there must be a formula that gives you a way to know with some...

Maybe this will be more helpful Problem You have a wood table with length of 3 meters and width of 2 meters. Ignoring the weight of the table, a 10 Kg weight is place at the exact center of the table. a) How much of the 10 Kg weight is each leg holding? If the weight was moved...

Currently they use a formula of taking the ratio between the length or width (dependent upon the side used) of where the Center of Gravity is located at. This ratio is what is used to then find the two components that make up the corner and determine the weight that is distributed. This of...

Homework Statement Problem is this. I am tasked with deriving a formula or equations that I can then input into an excel format. I am to take an equipment base that has four sides with supports at each of the four corners. I am to find the load that each one will hold base upon the Center of...
