Physics! Two blocks (m1 = 5.0 kg and m2 = 4.0 kg) sit on a ramp (incined at 25° with respect to the ground)?
Two blocks (m1 = 5.0 kg and m2 = 4.0 kg) sit on a ramp (incined at 25° with respect to the ground). They are held in place by wires. If the coefficient of static friction between the blocks and the ramp is 0.24, what is the tension in the wire between m1 and m2?
What is the tension in the wire between m2 and the wall?

0.24 is less than the tangent of 25° (0.466), so the tension is non-zero.
Specifically, the tension in the wire to M1 is the gravitational force along the plane minus the frictional force (μmg cos θ), or 5g(sin 25° - μ cos 25°)
For the second half, figure the net force on M2 after friction and add.
