Question

A uniform beam of length 7.60 m and weight 4.50 x 102 N is carried by two workers, Sam and Joe. Determine the force that each person exerts on the beam given that Sam is at a distance of 1.00 m away from one of the edge and Joe is 2.00 m towards the other edge of the beam. (Sam is walking towards Joe)

Answer 1

We have given:

Weight=P=4.5$\times 102$ N=459N,

Length=L=7.60m.

Let`s solve :

for Sam:

F_sam$\times$ 4.60m=P$\times$1.8m,

F_sam=459$\times$ 0.39=179.60N for Sam and

for Joe:

F_Joe$\times$ 4.60m=P$\times$2.8m,

F_Joe=459$\times$ 0.60=275.4N for Joe and

we have found answers.
