A uniform bar of length 34 m and mass 3 kg is attached to a wall with a hinge that exerts a horizontal force Hx and a vertical force Hy on the bar. The bar is held by a cord that makes a 90◦ angle with respect to the bar and 47 ◦ with respect to the wall. What is the magnitude of the horizontal force Hx on the pivot? The acceleration of gravity is 9.8 m/s 2 . Answer in units of N
