Question:

Anail is an example of a double inclined plane. true false

Answers

Wedges are a type of inclined plane. As a wedge is forced into a space in an object, it exerts force to widen the space. .. so wedges is like a nail.

A wedge is a double inclined plane. ... When a wedge is moved, it applies force on an object. It applies an output force greater than your input force. In the case of an axe, the output force is so great that it causes wood to split.

Explanation:

Left block is on surface with higher inclination so it will go down . If T be tension

For motion of block A ,

net force = mgsin60 - (T + mg cos 60 x μ ) , μ is coefficient of friction .

ma =  mgsin60 - T -  mg cos 60 x .1

10a = 277.13  - T - 16

= 261.13 - T

T = 261.13 - 10a

For motion of block B

T - mg sin30 - mgcos30 x μ = ma

T- 160 - 27.71 = 10 a

261.13 - 10a - 160 - 27.71 = 10a

73.42 = 20a

a = 3.67 ft / s²

common acceleration = 3.67 ft / s²

Conservation of energy. A ball rolls down a ramp, then up another ramp. Even if the ramps are set at different angles, the final height achieved by the ball is (almost) its original height.
