(1)
= 
Q = 32,800 N
now put this value in equation 1.
Deflection of B = 
= 0.0728 mm
Answer:
Check the explanation
Explanation:
Single Unit Truck ESAL = 43.38 + 5.16 = 48.54
Semi Unit Truck ESAL = 43.38+ 6.00+7.4 = 56.78
So total ESAL's during design life = (400*48.54 + 350*56.78)*365*10/18000 = (19416+19873)*3650= 3939
Kindly check the attached image
Here
Reliability = 95% = 0.95, therefore ZR = -1.645, S0 = 0.4, MR = 18
Delta PSI = 4.2-2.5= 1.7
Resilient Modulus = 18000 psi, So MR = 18
Assume SN = 3.0 for flexible pavements
There W18 calculates to 0.26807
So
log10 (3939) = 9.36*log10(SN+1) -.2/(.4+1094/(SN+1)5.19)) -6.01
Structural Number SN = a1*d1 + a2*d2 *m2 +a2*d3 *m3
= a1*d1 + a2*d2 +a2*d3
Answer:
Gravitational force (pulled downward by the Earth)
Normal force (pushed upward by the ground)
Applied force (pushed by the person)
Friction force (pulled opposite the direction of motion by the roughness of the ground)
Answer:21.3%
Explanation:
Given
80 % reduction in tool life
According to Taylor's tool life
=c
where V is cutting velocity
T=tool life of tool
80 % tool life reduction i.e. New tool Life is 0.2T
Thus


=1.213V
Thus a change of 21.3 %(increment) is required to reduce tool life by 80%
