haruspex said:ch side, but sin
for moment about A , i have 350(1) +CD(3) +200(3)+200(3√2)-FBZ(3√2) = 0haruspex said:I don't lnow why you have an extra 200 on each side, but since they cancel it doesn't matter.
You mean Faz and Fbz, no?
Which way does the force act in CD?
For choice of axis, it usually helps to pick a point with one or several unknown forces acting through it, so they do not feature in the equation. You will need equations for more than one axis, but they can pass through the same point.
You should be able to knock off Fax and Fay straight away.
To clarify, you can take moments about a point, but the moment you get will have an axis. That is, it will be a vector.BvU said:In a 3D world, moments are not about a point but about an axis.
As BvU indicates, this does not work. Those individual moments do not all have the same axis, so you cannot add them as scalars. Either find them as vectors, or take moments separately about the x, y, z axes through the point.werson tan said:for moment about A , i have 350(1) +CD(3) +200(3)+200(3√2)-FBZ(3√2) = 0
A moment on a semi quarter plate refers to the turning effect produced by a force applied at a certain distance from a fixed point on a semi quarter plate. It is a measure of the plate's resistance to being rotated around that fixed point.
A moment on a semi quarter plate is calculated by multiplying the force applied by the distance from the fixed point to the line of action of the force. This can be represented by the equation M = F x d, where M is the moment, F is the force, and d is the distance.
The moment on a semi quarter plate is affected by the magnitude and direction of the force applied, as well as the distance between the force and the fixed point. The shape and material of the plate can also impact the moment.
A moment on a semi quarter plate is only calculated for a portion of the plate, while a moment on a full quarter plate takes into account the entire plate. This means that the moment on a full quarter plate may be larger, as it considers a greater surface area.
Understanding moments on semi quarter plates is important in engineering and physics, as it allows for the prediction and analysis of the behavior of objects under different forces and distances. This knowledge is crucial in designing structures and machines that can withstand external forces and maintain stability.
