A package is at rest on a conveyor belt which is initially at rest The belt is started and moves to the right for 1.3s with a constant 'a' and comes to a stop after a total displacement of 2.2m. Knowing that the coefficients of friction between the package and the belt are /mu s =0.35 and /mu k =0.25.
(a) the decel 'a' of the belt
(b) the displacement x of package relative to the belt as the belt comes to a stop.
Consider the simply supported beam that has one external load applied to it. At a cross- section that cuts through the carriage bolt, there are 5 points at which the states of stress must be identified.
An incompressible fluid flows horizontally in the x-y plane with a velocity given by u = 33 (y/h)1/2, where y and h are in meters and h is a constant. Determine the average velocity for the portion of the flow between y = 0 and y =h
Modify function random0 so that it can accept 0, 1, or 2 calling arguments. If it has no calling arguments, it should return a single random value. If it has 1 or 2 calling arguments, it should behave as it currently does.
Calculate the vapor pressure, air pressure, relative humidity, and air density at elevation 1500 m if air temperature is 25 degrees C and dew point temperature is 20 degrees C and the lapse rate is 9 degrees C/km
The 30-Mg freight car A and 15-Mg freight car B are moving toward each other with the velocities VA= 20 km/h to the right and VB= 10 km/h to the left. the spring constant on car A is k= 3MN/m.
A dam located in a channel of rectangular cross-section which carries water flowing at a rate of 8.75m3/s. The depth of water upstream of the dam is 2.5m
A trapezoidal channel having bottom width of 8 m and side slopes of 1 : 1, carries a discharge of 80 m^3/s. Find the conjugate depth to an initial flow depth of 0.75 m before the jump.
Two 52 kN loads are maintained 2.5 m apart as they are moved slowly across beam AB. Write a computer program to calculate the deflection at the midpoint C of the beam for values of x from 0 to 9 m, using .5 m increments.
Determine rqd impeller diameter, Qactual, h_p-actual, E, BHP required for...., NPSH_R, max elevation at which the pump can be installed.
Determine a set of a rectangular beam design values b,d and As that will be needed to support a factored bending moment Mu= 450 Kip-ft. Use f'c= 4500 psi and fy= 40000 psi.
You are using that tape to measure the distance between two pointswhere the tapes are supported at the ends only. The temperature ofthe day is 68oF. What amount of tension do you need to apply not tohave any corrections in the tape measurement?
Normal load at failure was 93.8N with a maximum shear load of 38.7N. Find stresses on the failure plane, sketch a graph showing these on the shear stress and normal stress axes. Find the friction angle and shear strength.
