Answer
given,
mass of the person, m = 50 Kg
length of scaffold = 6 m
mass of scaffold, M= 70 Kg
distance of person standing from one end = 1.5 m
Tension in the vertical rope = ?
now equating all the vertical forces acting in the system.
 T₁ + T₂ = m g + M g
 T₁ + T₂ = 50 x 9.8  + 70 x 9.8
 T₁ + T₂ = 1176...........(1)
system is equilibrium so, the moment along the system will also be zero.
taking moment about rope with tension T₂.
now,
T₁ x 6 - mg x (6-1.5) - M g x 3 = 0
'3 m' is used because the weight of the scaffold pass through center of gravity.
 6 T₁ = 50 x 9.8 x 4.5 + 70 x 9.8 x 3
 6 T₁ = 4263
     T₁ = 710.5 N
from equation (1)
 T₂ = 1176 - 710.5
  T₂ = 465.5 N
hence,  T₁ = 710.5 N and T₂ = 465.5 N
 
        
             
        
        
        
Answer: Socratic
Explanation: i’m not sure but you can use Socratic it’s a good app that helps
 
        
             
        
        
        
The nucleus is the core of an atom which is made up of protons and neutrons. Every single type of atom has a dense center and the majority of the mass is located in here.
 
        
                    
             
        
        
        
Use the formula 1/2*I*w^2 where w is the angular speed and I is the rotaional inirtia (for disk it is .5*mass*radius^2).
