Question
7 A diver of mass 50 kg is positioned at the end of a 4 m long diving board as
shown below. The mass of the uniform board is 20 kg.
а.
The diving board is bolted down at only one of the supports. Which of
10m
diver's m- soky
the supports makes the most sense (A or B)? Answer by considering
the removal of the bolts, and then discuss the solution.
Board's m-2D Kg
m=20
→ Support A because Aacts as the paumany suppont eB a a
stcondary.
d between A UB-Im
diver's d from A =4m
b. Construct a free-body diagram showing all of the forces acting on the board. Use this
diagram to determine the magnitude and direction of the forces acting on support A and B.
