Question
![One end of a uniform meter stick is placed against a vertical wall. The other end is held by a lightweight cord that makes an angle 0 with
the stick. The coefficient of static friction between the end of the meter stick and the wall is H, = 0.400.
A. (2 points) What is the maximum value that 0 can have if the stick is to remain in equilibrium? Express your answer in degrees.
B. (4 points) A block of the same weight as the meter stick is suspended from the stick at a distance x from the wall, as shown below.
Assume that 0 =15.0° in this part of the problem. What is the minimum value of x for which the stick will remain in equilibrium?
Answer: x >
C. (4 points) When 0 =15.0°, how large must the coefficient of static friction be so that the block can be attached 0.100 [m] from the left
end of the stick without causing it to slip?
