Angle between arms of lever given effort, load and net reaction at fulcrum Solution

Follow our step by step solution on how to calculate Angle between arms of lever given effort, load and net reaction at fulcrum?

FIRST Step Consider the formula

θ = \arccos (\frac{(W^{2}) + (P^{2}) - ({R f'}^{2})}{2 \cdot W \cdot P})

Next Step Substitute values of Variables

∴

θ = \arccos (\frac{({2945N}^{2}) + ({310N}^{2}) - ({2966.646N}^{2})}{2 \cdot 2945N \cdot 310N})

Next Step Prepare to Evaluate

∴

θ = \arccos (\frac{(2945^{2}) + (310^{2}) - ({2966.646}^{2})}{2 \cdot 2945 \cdot 310})

Next Step Evaluate

∴

θ = 1.58824805294571rad

Next Step Convert to Output's Unit

∴

θ = 90.9999102536769°

LAST Step Rounding Answer

∴

θ = 90.9999°
