Webb13 okt. 2024 · Numerical problem on the calculation of tension force. Here in this problem, the coefficient of friction is equal to 1. This is very high friction, that is why you see a very low acceleration. We will apply the formula for tension as above and calculate the value of tension in the rope. We will verify using both blocks. WebbIf the angle of the incline is at an angle θ to the horizontal, then the magnitudes of the weight components are w = wsin(θ) = mgsin(θ) and w ⊥ = wcos(θ) = mgcos(θ). Instead of memorizing these equations, it is helpful to be able to determine them from reason. To do this, draw the right triangle formed by the three weight vectors. WebbWe resolve perpendicular to the plane (as the normal reaction R R acts at a right angle to the plane), where acceleration is zero. F =ma, R −mg cosθ =m×0, R =mg cosθ. F = m a, R − m g cos θ = m × 0, R = m g cos θ. Now we resolve in the direction of the slope, if the particle is at rest then F =ma, mg cos(90∘ −θ)−F =m×0, mg ... butts county historical society
