    Deriving the Hazard Rate Formula for F(t) = 1-Exp -((t-γ)/n))^β

    F(t) = 1-Exp -((t-γ)/n))^β f(t) = dF(t)/dt = Exp/n[(t-x)/n]^β-1 h(t) = f(t)/1-F(t) h(t)= β(t-y)^β-1/n^β The final answer: h(t)= β(t-y)β-1/n^β, Is the correct answer. But, I can't for the life of me work out why. Have I made a mistake in the f(t) derivation. Can anyone help?

    What is the formula for calculating the maximum deflection of a bike axle?

    Hi Studiot, thanks for your help - much appreciated. Sorry about the small Picture aswell, still learning :0 It is Indeed a tricycle; don't know why I put Bicycle. The two collars are attached to the frame in the form of bearing housings, which will support the load of the driver and the...

    What is the formula for calculating the maximum deflection of a bike axle?

    My Question... To find the maximum deflection of this axle, can the formula: (W*a/24*E*I)*(3*l^2-4*a^2) Will the total length simply be 370mm(wheel to wheel), or will I have to include the total length of the axle?
