Answer:
At a 4 percent annual growth rate in GDP per capita, it will take 18 years for GDP per capita to double.
Explanation:
- GDP stands for the gross domestic products. It is the basis to monitor the value of good and service in the market.
- According to rule of 70:
Number of years to double =
=
≈ 18 years
In this way in total of 18 years the GDP will be double at the constant annual growth rate of 4%.

Answer:
a) 159.07 MPa
b) 10.45 MPa
c) 79.535 MPa
Explanation:
Given data :
length of cantilever beam = 1.5m
outer width and height = 100 mm
wall thickness = 8mm
uniform load carried by beam along entire length= 6.5 kN/m
concentrated force at free end = 4kN
first we determine these values :
Mmax = ( 6.5 *(1.5) * (1.5/2) + 4 * 1.5 ) = 13312.5 N.m
Vmax = ( 6.5 * (1.5) + 4 ) = 13750 N
A) determine max bending stress
б = =
= 159.07 MPa
B) Determine max transverse shear stress
attached below
ζ = 10.45 MPa
C) Determine max shear stress in the beam
This occurs at the top of the beam or at the centroidal axis
hence max stress in the beam = 159.07 / 2 = 79.535 MPa
attached below is the remaining solution
