Components of the force in (x1, 2,3) is given by the vector f-fsuppose that you transform to a new set of orthogonal axes '2.f'3) at the same origin but rotated by +30° about the 3 axis. what are the direction cosines, i. e., the elements of the rotation matrix rz(+30), and label them clearly as done in class? a. b. using (a), what are the components of f in (r',23), .e., what are fi? can give magnitude.) show that they are equal. d. why must the magnitude of the forces (result in (c)) be equal? e. if fi 1, f2 -2, and fa 3 (in newtons), what is the vector f and its magnitude?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
