it just does. okay?

I really need help on it!! Can someone help me?
How do forces act on truss bridges?
There are many forces acting on a truss bridge compression, tension, and torsion. The truss bridge uses equilateral triangles to spread out the stress of the load on these forces along the hold structure.
How do you identify balanced forces?
The object the forces are acting on will not move, or will be moving at a constant speed (e.g. not accelerating). This is called being in 'equilibrium'.
Forces that act on a bridge?
Depends on the type of bridge. Suspension bridges, for example, have tension holding them up. All are acted upon by gravity, and to a lesser extent, the force of contact with the wind.
What tower supports a bridge cable?
In a standard suspension bridge the cables are supported by a Bridge Pylon or series of bridge pylons. The cables are supported upon these pylons and they serve to reduce the tension forces that would be required at the cable anchorages had the cables simply been installed straight across the bridge span.
When you lift an object up two forces act on it identify these forces?
When you lift an object up, the two forces acting on it are the force of gravity pulling it down and the force exerted by you to lift it up. The force of gravity is acting downwards on the object, while your force is acting upwards against gravity to lift the object.
Does the force of compression act on the Tower Bridge?
Compressive and tensile forces are present in all bridges, and it is the job of engineers to design bridges capable of withstanding these forces without buckling or snapping. Buckling occurs when compressive forces overcome an object's ability to handle compression, and snapping occurs when the tensile forces overcome an object's ability to handle tension. The best way to deal with these forces is to either dissipate them or transfer them. To dissipate force is to spread it out over a greater area, so that no one spot has to bear the brunt of the concentrated force. To transfer force is to move it from an area of weakness to an area of strength, an area designed to handle the force. An arch bridge is a good example of dissipation, while a suspension bridge is a good example of transference. Figures 6 and 7 illustrate tension and compression forces acting on three bridge types.
You hold an apple over your head Identify all the forces acting on the apple and their reaction forces when you drop the apple identify all the forces acting on it as it falls and the corresponding?
When holding the apple over your head, the main force acting on the apple is the force of gravity pulling it downwards, with the reaction force being the apple exerting an equal force upwards on your hand. When you drop the apple, the only force acting on it is still gravity pulling it downwards, but now there is no reaction force as the apple is falling freely.
Why did the galloping gertie collapse?
The bridge was constructed with no thought at all about aerodynamics and the dynamic effects of wind forces. According to bridge historian David P. Billington, at that time among suspension bridge engineers, "there seemed to be almost no recognition that wind created vertical movement at all."
What parts of a suspension bridge experience tension when a load is applied and what parts experience compression?
In a suspension bridge, the main cables experience tension as they support the weight of the bridge and any additional loads. The vertical suspenders, which connect the main cables to the bridge deck, also experience tension. Conversely, the bridge deck itself experiences compression, particularly at its midsection, as it is pushed down by the load. Additionally, the towers that support the cables experience compression due to the forces transmitted from the cables.
