Hi everyone!i have this physics equation problem,i really need to know how to solve this for me to pass my exam,can anyone help me please.. Question: 1.what mass will be sustained on a plane inclined at 32 degrees horizontal, by a force of 200 newtons pulling upward at an angle of 28 degrees to the plane? 2.What is the pressing force perpendicular to the plane in question # 1 (taking g = 10m/s) 3.A differential pulley has two pulleys, with radii of 175mm and 190mm respectively; what pull on the chain is necessary to raise 750 kilograms? Thanks! God Bless..
