What is the maximum weight that can be suspended on a 16 Kg poll, 3/5 from the end? The maximum tension of the 30 degree guy-wire is 1500 N. Find the horizontal and vertical forces exerted on the poll by the hinge.
what are the main points which create necessity of new railway line? explain in detail different types of surveys conducted in railway work.
A coal fired power plant can be modeled as a heat engine. If the power output of the plant is 200 MW and the thermal efficiency is 42%, determine the amount of coal used per day if the heat of combustion from the coal is 24,000 kJ/kg.
Sketch the SCS triangular and curvilinear UHs and the mass curve for a 100-mi^2 watershed which is 60% good condition meadow and 40% good cover forest land. The watershed consists of 70% soil group C and 30% soul group A.
A 1.50 L buffer solution is 0.250 M in HF and 0.250 M in NaF. Calculate the pH of the solution after the addition of 0.0500 moles of solid NaOH. Assume no volume change upon the addition of base. The Ka for HF is 3.5 x 10 -4 .
Calculate Earth's gravitational force on the Shuttle astronauts while orbiting at an altitude of 220 miles (or 354 km) above Earth's surface.
Set up life cycle diagram for both alternatives and calculate net present value (NPT) and annual cost for the life time.
Suppose a sample of the 90 °C air is put in a closed variable-volume chamber containing a mirror, and the pressure is raised at constant temperature until a mist forms on the mirror. At what pressure would the mist form
what are the interface design boundaries and issues for the design and installation of a new toilet for a building
A flat plate weighing 220 N slides down a 15 degree incline with a velocity of 2.5 cm/sec. A thin film of oil with a viscosity of 1.29 N.sec/m^2 separates the plate from the ramp. if the plate is 50 cm by 75 cm, calculate the film thickness in cm.
a 25-mm diameter steel cylinder 300-mm long falls, because of its own weight, at a uniform rate of 0.1 m/s inside a tube of slightly larger diameter. A castor-oil film of constant thickness is between the cylinder and the tube.
The two pulleys are riveted together to form a single rigid unit, and each of the two cables is securely wrapped around its respective pulley. If point A on the hoisting cable has a velocity v=0.9 m/s,
The velocity of the bed is limited to a maximum value of 150mm/s to the right and 300mm/s to the left; the acceleration is successively equal to 150mm/s^2 to the right, zero 150 mm/s^2 to the left, zero, etc.
