Tensile force formulas
A cylindrical steel beam is 2 inches diameter and 6 feet long. The modulus of elasticity is 30 x 1,000,000 psi. If the beam is subjected to a tensile force of 1000 lbs, what will be the resulting unit strain?
A. 16,000 psi
B. .002 ft-lbs/sq-in
C. 0.000064 ft/ft
D. .0000106 in/in
SEM212 - Aim of this demonstration is to use measurements of the load required to propagate a crack (tear) in packaging tape to determine its fracture toughness.
Determine the coordinates x' and y' of the centroid C of the area shown in the figure and calculate the moments of inertia of the area shown, about ox and oy axes.
The mean diameter of a conical friction clutch is 250mm with a width of the conical surface being 50mm. The clutch is lined with a material having a coefficient of friction of 0.25
Geometric angle of attack, The Piper Cherokee has a wing area of 170 ft2 and a wing span of 32 ft. Its maximum gross weight is 2450 lbs. The wing uses a NACA 65-415 airfoil, which has a lift slope of 0.10331deg^-1 and alpha(L=0)= -3.0deg. Assume th..

The humidity of air can be determined by use of two different thermometers; a 'dry bulb' thermometer and a 'wet bulb' thermometer. explain how these thermometers can be used to estimate the amount of water vapour in the air.
Hydrostatic relation, An empirical formula relating pressure and density for seawater w/ temperature held constant is
In the idealized model attached shown, m = 15 kg, k = 135 N/m, and the viscous damping ratio is 0.15. Assume that an external harmonic force F(t) = 15 cos 4 t acts on the system with F0=15 N and forcing frequency of 4 rad/s.
