A uniform box has a height, h, and a width, w. Its center of mass at its geometric centre; ie it is h/2 above its base and w/2 to the right of its left side. Which of the equations below gives the maximum angle you can tilt the box before gravity is able to make it tip over? W h D O sin 1 (h/w) O sin 1 (w/h) O cos 1 (h/w) O cos 1 (w/h) O tan 1 (h/w) O tan (w/h)
