Textbook Question

Chapter 17.1, Problem 17.40P

The mechanism shown is one of two identical mechanisms attached to the two sides of a 200-lb uniform rectangular door. Edge ABC of the door is guided by wheels of negligible mass that roll in horizontal and vertical tracks. A spring with a constant of k = 40 lb/ft is attached to wheel B. Knowing that the door is released from rest in the position θ = 30° with the spring unstretched, determine the velocity of wheel A just as the door reaches the vertical position.

reading is 0.4 mas SHOWN. Assume h₁ = 0.4 m, h₂ = 0.5 m. (a) Do you know the specific weight of mercury? (b) Do you know the specific weight of gasoline? (c) Do you know the specific weight of oil? (a) YHg = 133,000 (b) Ygas = 6867 (c) Yoil = 8829 eTextbook and Media Part 2 N/m³ N/m³ N/m³ A+ Gasoline t +B Oil -Mercury Attempts: unlimited Did you calculate the pressure difference between two locations using the correct specific weight? Did you assume that the pressures in fluid are the same in a horizontal plane even though they are in different tubes? Are the calculated pressures in a column of fluid always higher at lower elevations? Did you account for the fact that the two horizontal tubes of the U-tube are above the ground? Concepts: The pressure in a fluid is a function of the specific weight of the fluid and the height relative to a reference. Pressure is constant in a horizontal plane of a continuous mass of fluid. (a) What is the initial pressure difference? (PA-PB) (b) What is…
