The three hinged arch is composed of segments of a circle. Support points A and D are not at the same level.Determine:(a) the horizontal and vertical components of reaction at A and D.(b) the shear, thrust, and moment in the arch at point C.
If it is subjected to the load of 20kN and the soil provides a frictional resistance that is uniformly distributed along its sides of w = 3kN/m , determine the force at its bottom needed for equilibrium. Neglect the weight of the post.
The cart takes 5.00s to go from point A to point C, and the cart takes 1.90s to go from point B to point C. What is the cart's speed at point B. Express answer numerically to three significant figures in feet per second.
Consider a piston/cylinder arrangement that has a linear spring mounted such that as the piston rises to a certain point it will encounter the spring, which will offer a downward component of force as the piston rises further.
A train which is traveling at 80 mph applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 60 mph as it passes a point 1/2 miles beyonds A.
Determine the values of S and Z and the shape factor about the horizontal x axes. Use the web and flange dimensions given in the AISC Manual for making these calculations.
As a consulting engineer you are hired to evaluate the operation and the unit processes within the plant and make recommendations for improvements. You are asked to consider the following units.
A solution contains 300 mg/L of acetic acid. Determine the pH of the solution if an equivalent amount of sodium hydroxide (NaOH) is added to it. Determine the concentration of NaOH required (in mg/L).
A cantilever beam of length 50 ft is embedded in a wall at A and has a free end B. A concentrated load of 100 kips upward is located at x = 25 ft from A. A uniformly distributed load of 20 kips/ft downward extends from 25 to 50 ft.
Slider A moves in the horizontal slot with a constant speed v = 1.90 m/s for a short interval of motion. Determine the angular velocity of bar AB if the displacement xA = 90 mm, and the length L = 440 mm.
