Create a 60 degree inclined plane utilizing various building components, string, as single pulley , and a scientific mass. attach one end of the string to the scientific mass (resistance force) and the other end to a force-measuring device. Place the scientific mass on the inclined plane and string over the pulley. Using a force-measuring device, pull the string and determine the force needed to obtain static equilibrium.
b. calculate the ideal mechanical advantage of the inclined plane system described above.
c. Calculate the ideal effort force needed to overcome the known resistance force.
When P = 800 lb, A) Draw the shear and bending moment diagram along its length; B) Determine the maximum tensile and compressive bending stresses; and C) determine the maximum shear stress.
The static pressures upstream and downstream of the screen are 0.2 and 0.15 psi and are uniformly distributed over the flow cross section area. Neglecting the force exerted by the duct wall on the flowing air, calculate the screen drag force.
At 100 km downwind (y=10m), what is the concentration of NOx in g/m^3. The wind speed at the top of the stack with a height of 100m is 6.5 m/s and an inversion layer of 750m Pressure air = 95kPa
An element of material subjected to a plane strain has a strain epsilon x of 280x10^-6, a strain epsilon y of 420x10^-6 and an engineering shear strain gamma xy of 150x10^-6.
Using estimates of rainfall, evaporation, and water consumption, the town engineer developed the following model of the water volume in the reservoir as a function of time
A-Olympus Mons, a 69,000-foot-tall mountain on Mars, is the largest volcano in the solar system. Its circumference at the base is large enough to cover almost the entire state of Colorado.
a particle moving along a straight path decelerates according to a = -kv. this represent a drag-induced deceleration. assume that the intial velocity is vo at t=0 and s = 0. determine the velocity of the particle both
Offshore in deep water, a wave gage measures the height and period of a train of waves to be 2m and 7.5 s respectively. The wave train propagates toward the shore in a normal direction without refracting and the nearshore bottom slope is 1:40.
