Answer:
The burden distance is 7 ft
Solution:
As per the question:
Specific gravity of package emulsion,
Specific gravity of diabase rock,
Diameter of the packaged sticks, d = 3 in
Now,
To calculate the first trail shot burden distance, B:
B = 7 ft
Answer:
Explanation:
Given data
Length L=2.5 m
Radius R=d/2=30/2 = 15 mm
Torque based on allowable stress
Allowable shear stress τ=50 Mpa
Allowable torque T=(π/2)τc³
Torque based on allowable angle of twist
Allowable Angle of twist
Ф=7.5°
Ф=7.5×(π/180)=130.90×10⁻³ rad
Allowable torque
T=(GJФ)/L
T=(G(π/2)c⁴)Ф)/L
T=(πGc⁴Ф)/2
Maximum Power Transmitted
Maximum power transmitted is given by
