midnight Saturday (05/03/14) Lab #7 Answers will be posted by 11am
on Sunday (05/04/14) Final Quiz next week will have 20
questions selected from Lab #1 #7 Lab Report #7 and Student Survey will
be due next on the class day
Deflection of a Cantilevered Beam
Measure deflection of a cantilevered beam due to a Point Load at different distances from the fixed support
Determine the elastic modulus of the beam material, and compare it with values from the handbook and Lab #5
Compare the measured deflections with values calculated from theory
Key Relation in Bending
At any location x along the longitudinal axis of the beam:
(x) is the curvature of the beam(x) is the radius of curvature of the beamM(x) is the internal bending momentE is the elastic modulus of the beam materialI is the moment of inertia of the beam cross-
section
Curvature of a curve y(x)
If deflections y(x) are small, then the slopes |y’(x)| << 1.
Cantilevered Beam under its own weight (=w per unit length)
Deflection of a Cantilevered Beam under its own weight
Cantilevered Beam with a Point Load P at a distance q
Deflection of a Cantilevered Beam with point load P
Deflection of a cantilevered beam with a point load P
