A curved rectangular bar has a mean radius of 6 in and cross section width b=2.5 in and depth h =1.5 in. 1. Determine the distance between the centroid and the neutral axis of the cross section.
mechanical vibrations a helical spring of stiffness k is cut into two halves and a mass m is connected to be 0.5 s. if
Immediately before failure, the testing machine records a force (F) of 50N, and a deformation (δ) of 2mm. We need to determine the maximum flexural strength (σ)
aif a rod of 1025 steel 0.5 m 19.7 in long is heated from 20 to 80 deg c 68 to 176 deg f while its ends are maintained
a l-shaped bracket lying in a horizontal plane supports a load p as shown. the bracket has a hollow rectangular cross
Block B of the mechanism is confined to move within the slot member CD. If AB is rotating at a constant rate of AB = 3rad/s, determine the angular velocity and angular acceleration of member CD at the instant shown.
Describe IN DETAIL how you could determine the required rate of heat addition or removal.
now consider the cooling process. it takes place in a heat exchanger hx. warm air. at 75 f is flows into one side of
Prove that the transformation Q1 = q12 Q2 = q2 sec p2 p cos p2 - 2q2 P= 1 P2 = sin p2 - 2q1 1 2q1 cos p2 is canonical, by any method you choose . Find a suitable generating function that will lead to this transformation.
The wheel of a crane lift is rolling on a flat rail. The radius of the wheel is 4 in, the contact length and force are 2.5 in and 1 ton respectively, and E = 30 MPa and ν = 0.3 for both parts. Determine (a) the maximum contact pressure, (b) the wi..
