A car and its suspension system are idealized as a damped spring-mass system, with natural frequency 0.5Hz and damping ration of 0.2. Suppose the car drives at speed "v" over a road with sinusoidal roughness. Assume the roughness wavelength is 10m, and its amplitude is 20cm. At what speed does the maximum amplitude of vibration occur, and what is the corresponding vibration amplitde.
Determine the resultant of the three forces F1 = 2.0i + 3.3j - 2.6k; F2 = - i + 5.2j - 2.9k; and F3 = 8.3i - 6.6j + 5.8k, which are concurrent at the point (2, 2, -5.). The forces are in Newton's and the distances are in meters.
The tank has a 180 mm inside diameter and a 12 mm wall thickness. Knowing that the tank contains compressed air under a pressure of 8 MPa, determine the magnitude T of the applied torque for which the maximum normal stress in the tank is 75 MPa.
If the trap door's weight is 50N. Calculate the tension in the string and the reaction at the hinge.
why does a car engine stop when we turn the key even when the vehicle is running? the engine should run on alternator
Determination of the open-loop system
Calculate the magnitude of the moment acting at the build-in end and specify the orientation of the moment vector relative to the principal centroidal axes of the section with the aid of a sketch and determine the stresses at each corner of the bu..
the water level in a tank is 20 m above the ground. a hose is connected to the bottom of the tank and the nozzle at the
If it is known that the value of the stress exponent n for this alloy is 8.2, compute the steady-state creep rate at 1300 K and a stress level of 89 MPa.
A small droplet of liquid detergent, falling through air in a spray drying tower, has its diameter reduced as water evaporates from the surface. If we assume that the temperature of the liquid within the drop remains at 290 K and the dry air is at..
Wind turbines are becoming more and more common as a method of energy production, wind turbines by their very nature are dynamic and are subject to and create their own internal and external kinematics and kinetics.
Calculations that show the material composition (fibre and matrix type and volume fractions) will meet the property specifications, and a justification of why this material composition is the cheapest option
Given that an activity's normal time and cost are 10 days and $400 and its crash time and cost are 5 days and $800, what is the activity's slope?
