Explanation Calculation: To solve this, sketch the situation on the coordinate system as shown below in Figure 1. Figure 1. The forces are in equilibrium and the resultant is zero. Find the horizontal components as follows: T R cos 37 ° + T L cos 120 ° + 215 cos 270 ° = 0 T R cos 37 ° + T L cos 120 ° + 0 = 0 T R cos 37 ° + T L cos 120 ° = 0 ... ( 1 ) Calculate the vertical components as shown below. T R sin 37 ° + T L sin 120 ° + 215 sin 270 ° = 0 T R sin 37 ° + T L sin 120 ° − 215 = 0 T R sin 37 ° + T L sin 120 ° = 215 ... ( 2 ) Solve the equation (1) and (2) as follows: T R cos 37 ° = − T L cos 120 ° T R = − T L cos 120 ° cos 37 ° T R = − T 1 ( − 0

Question

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
