You are asked to design a winch system for Santa's sleigh. Assume that Santa weighs 300 lbs, visits 10 houses an hour and requires a 20 foot lift at each house, what is the average power that the system will use if it is perfectly efficient?
A 4x4 carries an axial compressive force caused by dead, love, and roof live loads. Lumber is No. 1 Douglas Fir-Larch. Cm = 1.0 , Ct = 1.0, Ci = 1.0. The unbraced length of the member is 12 ft.
what value for Fy are the two forces F1=4i+Fyj+20K(N) and F2=8i-5j+7k(N) perpendicular to each other
what is the equivalent PF rate constant that would be used to describe treatment in a series of three CM reactors in terms of flow (Q), the total volume in the system (V), and the rate constant observed for the CM system
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.
A horizontal curve is being designed around a pond with a tangent length of 1200 ft and central angle of 0.5211 radians. If the PI is at station 145 + 00, determine the station of PT.
The volume flow rate of streams into the pipe is given by QA = 0.02t m 3 /s and that of stream B by QB = 0.008t 2 m 3 /s, where t is in seconds. The exit area of the pipe is 0.01m 2 . Find velocity and acceleration of the flow at exit at t = 1s.
An engineering student is driving on a level roadway and sees a construction sign 180 m ahead in the middle of the roadway. The student strikes the sign at 56 kph. If the student was traveling at 90 kph when the sign was first spotted, what was th..
A supertanker has length, breath, and draught (fully loaded) dimensions of 325m, 48m, and19m, respectively. In open seas the tanker normally operates at a speed of 115 kt (1 kt=0.515m/s).
A design for a hovercraft is made. A fan sends air in from the top of the rectangular chamber (60F) and is exhausted between skirts and the ground. Pressure in the chamber is responsible for lift, and the craft is 15 by 7 ft.
A multinational engineering consulting firm that wants to provide resort accommodations to certain clients is considering the purchase of a three-bedroom lodge in upper Montana that will cost $250,000.
Consider a small simple Rankine Power cycle which produces 600kW power from an electric generator with an efficiency of 95%. The steam leaves the boiler at 1250psia as superheated steam and leaves the turbine at 2 psia with a quality of 90%.
Each of the three partners realizes that in order for the firm to continue at the present rate of growth a realistic business continuation plan must be in place which would include a viable by-sell agreement between the shareholders.
