Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

The air temperature inside a hot-air balloon is 80oC, while the surrounding atmospheric air temperature is only 15oC. The mass of the empty-balloon material is 10 kg. When inflated completely, the volume of hot air within the balloon is 5000 m3 . Determine the maximum mass of the load that the balloon can lift from the ground in this situation. Given: ρair (at 15oC) = 1.22 kg/m3 , ρair (at 80oC) = 1.01 kg/m3 . If only 80% of the maximum load mass is used, what would be the balloon’s initial acceleration upward (neglecting any air drag effect)?
