Question
Transcribed Image Text:Learning Goal:
To use the equations of equilibrium to analyze a system
containing a wedge and to determine the necessary applied
force to introduce motion into the system.
Determine the normal force No that the crate exerts on the wedge when the system is at rest.
Express your answer to three significant figures and include the appropriate units.
The crate shown is held against wedge B by a spring. The
spring is 96.0% of its original uncompressed length
l= 3.00 m, and the spring constant is given as
k = 1750 N/m. The coefficient of static friction at all
contacting surfaces is us = 0.150. The mass of the crate is
m = 23.0 kg . The angle is 0 = 13.0°. Neglect the mass of
the wedge. Assume the crate only moves in the y direction
and that wedge A cannot move.
