A floor is to be supported on hardwood timber joists that are spaced at 0.5m centres and span 5.0m. The joists support flooring 20mm thick and an applied live load of 2kN/m2
Design a typical joist 50mm wide
Given data;
Density of timber = 800kg/m3
Bending Stress limit = 11.0 MPa
Shear Stress Limit = 1.0MPa
Youngs Modulus = 10.5 x 10^3 MPa
At the instant when angle theta= 50 degree, the horizontal guide is given a constant upward velocity v0 = 1.3 m/s. For this instant calculate the force N exerted by the fixed circular slot and the force P exerted by the horizontal slot on the 0.60..
