Homework Equations
The Attempt at a Solution
I want to first make sure I understand the problem properly. Please verify each of my statements. If there is no force F acting on the (large) triangular block, then the large triangular block will move to the right. The small triangular block will slide down the large block depending on the coefficient of static friction. If the static friction is strong, the small block will stay put. If friction is too weak, the block will slide down the larger one. So far, so good?
Once the force F acts on the large block, the situation is chaged. Now the forces acting on the large bock are:
- Gravity
- F
- Normal force due to surface between floor and large block
- Reaction force due to normal force due to surface between large and small block
Forces acting on the small block:
- Gravity
- Normal force due to surface between large and small block
- Frictional force due to friction in the surface between large and small block
Is this correct so far?
Next, having defined all the forces present, I want an intuitive understanding of the acceleration of each block. Obviously this will depend on F, but assuming we know F, can we correctly say that the large block will accelerate to the left with a certain acceleration we can calculate, and that the small block will accelerate up the large block? I am a bit confused about the smaller block's motion.
What are we solving for in this problem? Also, please read between the lines of my post and post accordingly. My main confusion regards the interdependence between F, the large block, and the small block.
All help is appreciated. Thanks.
