A uniform 6.84 m long horizontal beam that weighs 316 N is attached to a wall by a pin connection that allows the beam to rotate
. Its far end is supported by a cable that makes an angle of 55◦ with the horizontal, and a 608 N person is standing 1.9 m from the pin. 1.9 m 6.84 m 608 N 316 N R FT 55◦ Find the force FT in the cable by assuming that the origin of our coordinate system is at the rod’s center of mass.
Let us assume that moment about the pin and then setting it equal to zero as the rod is in equilibrium is as follows.
Moment = Force × Leverage
= 0
Therefore, we can conclude that the force () in the cable by assuming that the origin of our coordinate system is at the rod’s center of mass is 935.11 N.
The obstruction offered by the battery is known as its internal resistance. Electricity is produced by the chemical reactions inside the battery. The pace of the responses is straightforwardly relative to the temperature and the power delivered by the battery increments. In this way, the inward opposition of the battery increments as diminishing the temperature.
The battery is a gadget which generates electrical energy by the chemical reactions that takes place inside it.
In this way, the announcement a battery is a gadget that produces electricity by the transformation of chemical energy into electrical energy is valid.
The potential difference between the terminals of a battery, when no current is streaming into an outer circuit is called emf of the battery and if the potential distinction is measure when the current is streaming into the outside circuit is called terminal voltage
.
The battery attempts to move the negative charge from the low potential terminal to the high potential terminal of the battery. The potential vitality of the negative charges is high at the lower potential terminal and the potential vitality of the negative charge is low at the high potential terminal. Along these lines, the battery attempts to move the charges from high potential terminal to low potential terminal.
25 miles at 42.5 degrees east of south. (20^2+15^2 =C^2...You get 25 miles...East of South because she traveled a longer distance to the East. Then you find the angle between the original and ending point.) Hope it helps. You may ask me any other questions.
