A steel ramp is used by a worker in a factory to move a cardboard box. The box weighs 40 lb with a center of gravity at point G, the force applied by the worker is parallel to the ramp and the coefficient of friction between the box and ramp is μs = μk = 0.3. Determine the force the worker must apply to slide the box down the ramp. Determine the friction force F acting between the ramp and the box if the worker slid the box up the ramp

Figure (a) shows the cross-sectional dimensions for the structural steel section known as C1020 (channel with a nominal depth of 10 in., weighing 201b/ft). The American Institute of Steel Construction Structural Steel Handbook lists the following properties for the cross section: A=5.88in.2,Ix=78.9in.4, and Iy=2.81in.4. If two of these channels are welded together as shown in Fig. (b), find Ix and Iy for the resulting cross section.
