This assignment is due at the start of lecture on the due date posted on Canvas. Problem 1. For the spring board shown in the figure, if the spring at point A stretches and increases in length by 7.85 cm and the spring at point B compresses and decreases in length by 10.46 cm, what will be the angle that the diving board makes with horizontal? 1 m Problem 2. For the crate supported in the figure, determine the lengths of the ropes AB and AC. 4 ft

Explanation / Answer

The height A is

h1 = 7.85 cm

the height at B is

h2 = -10.46 cm

Now from right angle triangle,

opposite side = h1-h2 = 7.85+10.46 = 18.31 cm

adjcent side = 1m = 100cm

the angle of orientation is

tan theta = opposite side/adjcent side = 18.31/100 = 0.1831

theta = 10.38 deg
