Question

Calculate the position of the persons CoG when :

Wb= the weight of the board (98N)?

Fr= the reaction force exerted by the scales on the reaction board (570N) ?

r = the distance between the pivot and the reaction force 1.900m ?

b= the distance between the pivot and the CoG of the board (0.950 m) ?

p= the distance between the pivot and then CoG of the person ? 

 

 

 

r- 1.74m
b= the distance between the pivot and the CoG of the board=1.74/2=0.87
p= distance between pivot and the CoG (Unknown = c of G)
