I am completing a work pack as preparation for an exam coming up. The questions have moved onto beams and the question is very dissimilar to the examples I've been given and I am having trouble progressing, and unsure of any answers I produce. The question is separated into 5 parts.
I have linked the question in the picture below.
Any help would be greatly appreciated. Thanks© BrainMass Inc. brainmass.com October 25, 2018, 9:22 am ad1c9bdddf
Length of the beam, L = 2+1+5+2 = 10 m
R1 + R2 = 5*10 + 10 + 20
=> R1 + R2 = 80 ...(1)
Moment of forces about R1 (anti-clockwise +ve):
R2*6 - 20*(1+5+2) - 5*(1+5+2)*(1+5+2)/2 - 10*1 + 5*2*2/2= 0
=> R2*6 = 320
=> R2 = 320/6 = 160/3 kN = 53.33 kN --Answer
Hence, from Equation (1):
R1 = 80 - 160/3 = 80/3 = 26.67 kN --Answer
From left end:
x = 0 to x = 2m (left side), shear force,
F = -5*x
At x = 0, F = 0
at x = 2m, F = -10 kN
x = 2 (right) to x = (2+1) = 3m (left):
F = ...
