2. Question 1
Determine the value for W1 so that the weight W does not move. W =100 kG
s = 0.25

3. s = 0.25 x y N F
45o W1 W
Sliding down the ramp.

4. s = 0.25 x y N F
45o W1 W

5. W1
s = 0.25 W F x y N
45o
Sliding up the ramp.

6. s = 0.25 x y N F
45o W1 W

7. Question 2
A horizontal force of P=100N is just sufficient to hold the crate from sliding down the plane, and a horizontal force of 350 N is required to just push the crate up the plane. Determine the coefficient of static friction between the plane and the crate, and find the mass of the crate.
