1.	A cubical block is subjected to three forces F1=20 N acting at an angle of 45∘ with horizontal and lying in the diagonal plane of the cube, F2=30 N along y−axis and F3=40 N acting in the negative x−direction as shown. Find the magnitude of friction force acting on the body.
Answer» A cubical block is subjected to three forces $F_{1} = 20 N$ acting at an angle of $45^{\circ}$ with horizontal and lying in the diagonal plane of the cube, $F_{2} = 30 N$ along $y -$ axis and $F_{3} = 40 N$ acting in the negative $x -$ direction as shown. Find the magnitude of friction force acting on the body.
