Step 1

To find the angle that F makes with the z-axis, we can use the fact that the sum of the angles in a triangle is 180 degrees. Since we know the angles F makes with the x and y axes (76° and 86°), we can subtract these angles from 180° to find the angle with the Show more…

A force F is applied to a corner of a rectangular cube as shown. The force has a magnitude of 577 N and makes angles of 76°, and 86° with the x, and y axes respectively. Determine: (a) the magnitude of the moment of F about axis OA, (b) the components of the moment (of the vector) of F about axis OA. Hint: You first need to find the angle that F makes with the z axis. 1 0 1.3 m 2.8 m 4.1 m
