Question

if effort applied at the end of handle of screw Jack having length 110 mm is the 100 Newton calculator is applied at the end of handle​

Answer 1

Answer:

your answer

Step-by-step explanation:

In a screw jack, the effort required to lift the load W is given by (where α = Helix angle, and φ = Angle of friction)

A. P = W tan(α - φ)

P = W tan(α + φ)

P = W tan(φ - α)

P = W cos(α + φ
