Question

A 3.0-m-long rigid beam with a mass 130 kg

is supported at each end. An 75 kg
student stands 2.0 m
from support 1. How much upward force does support 1 exert on the beam? How much upward force does support 2 exert on the beam? Answer in Newtons

Answer 1

Step-by-step explanation:

Support one 1/2 of the beam + 1/3 of the student

( 65 + 25 )(9.81) = 882.9 N

Support two 1/2 of the beam + 2/3 of the student

(65 + 50)(9.81) = 1128.15 N
