Remember the Tilikum Crossing bridge we looked form last week? Now let's take it to realistic 3D problems. If the cables were tightened such that the tension in cables C is 4000 kN and the tension in cable B is 2000 kN. What is the moment of forces (the forces from two cables) on point O (bottom of the pier)? ( use scalar approach. Make sure to put unit and direction!) 28m 15m 12m B. 12m 28m 15m wos

Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force between two massive objects or electrostatic forces between two charged particles. So from atoms to planets, the central forces play an important role in shaping our daily lives. One of the remarkable features of central forces is that they are conservative, i.e. the total energy of a central force system can always be expressed as a gradient of a potential energy function.
