Determine the magnitude of reaction at point A (in kips) of a 20' beam with 5kips at 4' of the beam and 2kips at 9' of the beam at 350lbs./ft.

The grains of wood in the board make an angle of 20 degrees with the horizontal as shown. Determine the normal and shear stresses that act perpendicular and parallel to the grains if the board is subjected to an axial load of 250 N.(Dimensions l=300mm, w=25 mm, h=60 mm)

2. A beam having an overall length of 24 has a 4 overhang at one end. The left support is a pin connection, and the right connection is a roller. A concentrated downward force of 2000 lb. is located 6 from the left support, and a uniformly distributed load of 200 lbs./lin. ft. begins 6...

normal and shear stresses that act perpendicular and parallel to the grains if the board is subjected to an axial load

the semicicular three-pinnned arch has a uniform square cross-section of depth 5cm and made of material with elastic modulus E=30 x 10^8kN/m^2. The radius of the arch is 10m and it is subjected to a vertical load of 10kN at the point C. Ignoring both axial and shear deformations and using the...

use laplace transform to solve differential equations. y''+2y'+y=8e^2t with y(0)=1 and y'(0)=1

WTF IS THIS?!?!?!?!?!?!?!?!?!?!?!??!?!?

If the discharge is 500 cfs, what power output may be expected from the turbine

A floor structure is shown diagrammatically in Figure 1, consisting of a beam, BC that is simply supported on the tips of two cantilever beams, AB and CD. The system carries a complete uniformly distributed load of 4 kN/m. Sketch the shearing force and bending moment diagrams for the simply...
