Total Normal Force Acting on Slice given Weight of Slice Solution

Follow our step by step solution on how to calculate Total Normal Force Acting on Slice given Weight of Slice?

FIRST Step Consider the formula
Fn=W+Xn-X(n+1)-(Ssin(θπ180))cos(θπ180)
Next Step Substitute values of Variables
Fn=20N+2.89N-9.87N-(11.07Nsin(45°π180))cos(45°π180)
Next Step Substitute values of Constants
Fn=20N+2.89N-9.87N-(11.07Nsin(45°3.1416180))cos(45°3.1416180)
Next Step Convert Units
Fn=20N+2.89N-9.87N-(11.07Nsin(0.7854rad3.1416180))cos(0.7854rad3.1416180)
Next Step Prepare to Evaluate
Fn=20+2.89-9.87-(11.07sin(0.78543.1416180))cos(0.78543.1416180)
Next Step Evaluate
Fn=12.8694686736617N
LAST Step Rounding Answer
Fn=12.8695N
