Question

Figure (a) shows a uniform ramp between two buildings that allows for motion between the buildings due to strong winds. At its left end, it is hinged to the building wall; at its right end, it has a roller that can roll along the building wall. There is no vertical force on the roller from the building, only a horizontal force with magnitude Fh. The horizontal distance between the buildings is D = 4.00 m. The rise of the ramp is h = 0.559 m. A person walks across the ramp from the left. Figure (b) gives Fh as a function of the horizontal distance x of the person from the building at the left. What are the masses of (a) the ramp and (b) the person? (Note: On the picture a=5.00 and b=10.0)

Explanation / Answer

a)M = (Fh/g),g = 9.8 m/s^2

b)m = Fh x (0.559/4.00)
