thus the turning effect produced by force is known as moment of force or torque. now we will consider the example of a door and try to formulate the equation for torque. if we apply force closer to the hinge, then a larger force is required to rotate the door. also, it depends on ...
Circle and Its Equation: A circle is the locus of all those infinite points that forms a round closed path around a fixed point and maintains a constant distance from the fixed point. This fixed point is called the center and constant distance is termed...
What is the circle equation?The general equation of a circle is:x2 + y2 + Dx + Ey + F = 0 The "center-radius" form of the equation is:(x − h)2 + (y − k)2 = r2 ...where the h and the k come from the center point (h, k) and the r2 comes from the radius ...
