Because momentum effect the ability of the driver to stop on time.
If gravity increases, the bridge is subjected to more weight. If gravity decreases, the bridge is subjected to less weight. Either way, the bridge will have a maximum weight that will remain the same regardless of the gravitational environment.
The term "galvanometer", in common use by 1836, was derived from the surname of Italian electricity researcher Luigi Galvani, who discovered in 1771 that electric current could make a frog's leg jerk. The deflection of a magnetic compass needle by current in a wire was first described by Hans Oersted in 1820. The phenomenon was studied both for its own sake and as a means of measuring electrical current. The earliest galvanometer was reported by Johann Schweigger at the University of Halle on 16 September 1820. Andre-Marie Ampere also contributed to its development. Early designs increased the effect of the magnetic field due to the current by using multiple turns of wire; the instruments were at first called "multipliers" due to this common design feature.
Galvometer works on the principle of conversion of electrical energy into mechanical energy. It is an instrument used to indicate the presence, direction or strength of a small electric current.
The creation of electric current in a conductor moving in a magnetic field was discovered by Faraday in about 1825, but he didn't know why it happened. Fundamentally, it is due to the attraction/repulsion between the magnetic field and the free electrons in the conductor, so that when the conductor moves it causes the electrons to move, which comprises the current. A similar effect can be obtained if the conductor is still and the magnetic field moves. These effects are the absolute fundamental reasons for being able to generate electricity using rotating machines, which are designed with different characteristics but all make use of the above physical facts
To measure small amounts of current in a circuit, it is utilized with the motor effect.
The answer is the weight of the bridge design you build
A motor effect is when magnetic flux lines interact with the current flow in the current conducting wire (a production of current means there is a production of a magnetic field, thus the magnetic field of a permanent magnet interacts with the magnetic field of the current), hence causing a motor effect, where electric energy is transformed into mechanical energy. In a galvanometer, the concept of the motor effect is used for it to detect and measure the magnitude of small electric currents as an instrument. A galvanometer uses radial magnets which cover more area of the rotor (this is where the needle is attached), as this rotor consists of an armature and loops of wire, it is perpendicular to the magnetic flux lines of the radial magnet. Therefore as the current flows through the coil, a magnetic field is produced, and the motor effect occurs allowing the needle to move on the scale.
yes definately..
Sharing will cause the bridge to collapse.
Weather effect
You are thinking of an above the ground aqueduct. They were, in effect, a bridge for a water pipe.
The load of a bridge is the amount of weight that can be distributed throughout the bridge without collapsing. Engineers take into effect, wind, rain, and earthquakes when calculating the load.
You could atleast know were it went.
A non rated driver is usually one that doesn't effect the rate.
The primary effect of gravity on a bridge is that it keeps it "in place" in the wind. The massive weight of the bridge is a key part of its structure and of its structural integrity. Certainly gravity acts to "pull the bridge down" in effect, but we use that to stabilize the structure, turning a "negative" into a "positive" in that light. Gravity transfers forces to the structures that support the bridge, and, in the case of (most) suspension bridges, hold the ends of the main cables to the massive blocks set to maintain the tension of those cables.
