A 170-kg uniform steel beam 8.25 m in length rests against a frictionless vertical wall, makding an angle of 50.0° with the horizontal. A 70.0-kg construction worker begins walking up the beam. The coefficient of static friction between the beam and the ground is 0.750. What are the horizontal and vertical forces exerted on the beam by the ground when the worker has walked 3.00 m along the beam? (Enter the magnitude.) Fhorizontal Fvertical = Need Help?
