A hot-metal ladle and its contents have a mass of 50 Mg. Knowing that the coefficient of static friction between the hooks and the pinion is 0.30, determine the tension in cable AB required to start tipping the ladle. Note: the simplification sin (tan−1 μ) ≈ μ is NOT used in the solution of journal bearing and axle friction problems. While this approximation may be valid for very small values of, μ there is little if any reason to use it, and the error may be significant. For example, in Problems 8.76€“8.79, 0.50, s μ = and the error made by using the approximation is about 11.8%.
