The problem involves two blocks on a slope, with specific masses and friction coefficients provided. The original poster seeks to determine the maximum force needed to keep the blocks together without falling, considering the effects of static and kinetic friction.
The discussion is ongoing, with participants exploring the relationship between the forces and acceleration. Some guidance has been offered regarding the typical angle used in similar problems, but no consensus has been reached on the correctness of the calculations.
Participants note the absence of friction between one block and the floor, while discussing the specific friction coefficients for the interaction between the two blocks. There is also a reference to a common angle used in related problems, which may influence the calculations.
So what does that imply regarding your acceleration variable, a?shashlik said:

Typically an angle of 37 degrees is specified when the author intends a 3-4-5 triangle. Taking cos of it to be exactly .8, and using 10m/s##^2## for g, gives 11.2N exactly.shashlik said:
