Question:

Which specification has been written on the outer frame can not park the basket platform

Constantly rising hydrogen balloon and basket total weight of 100N, by the air buoyancy (buoyancy direction is always vertical up) to 120N. Seeking: in the process of hydrogen ball and the basket by the resultant force is how much? What is the air resistance of the hydrogen ball and the basket? If the hydrogen balloon and the basket in the air when the buoyancy and resistance are the same size, then the hydrogen balloon and the basket to the original rate of uniform decline, should be added in the basket with the weight N objects? More

Answer:

When the hydrogen balloon and the basket are rising at a constant speed, the vertical downward gravity G = 100N, the vertical downward air resistance f, the vertical upward buoyancy force F = 120N, is in equilibrium, : G + f = F, the air resistance f = FG = 120N-100N = 20M, the direction of vertical down; A: hydrogen ball and basket by the air resistance is 20N, vertical direction down When the hydrogen balloon and the basket fall uniformly, the vertical upward gravity G ', the vertical upward air resistance f = 20N, the vertical upward buoyancy F = 120N, is in equilibrium, : G '= F + f = 120N +20 N = 140N, it should be added in the basket for the weight △ G = G'-G = 140N-100N = 40N; A: hydrogen ball and the basket when the uniform decline, Should be added in the basket with a weight of 40N objects
in the construction of the height of the basket should be set up with the relevant operating personnel with the safety belt And safety lock, and we need to pay attention to is the safety rope should be fixed in a reliable location, can not be connected with any part of the basket
In the construction of the external wall of the installation process of the requirements and norms, this Rieter electric basket to give you summed up:
