Problem of finite element analysis(urgent)

By Himanshu Dhadwal on

Consider the truss system shown in Fig. 2 modelled by three elements. The element numbers are shown in brackets. The node numbers are as indicated in the figure. Suppose that all the trusses have a cross sectional area of A = 0.1 m2 and Young’s modulus E = 70 GPa. Determine the displacements at all the nodes if the force P = 2000 N. The length L = 2 m.truss.jpg

truss: simply supported right-angle triangle truss

By ngcobo bh on

A simple supported right-angle triangle truss of 1/2( 5 x 12 ) meter square, is subjected with 50KN and 25KN at the mid-span and top end of the truss respectively. The truss is having two internal members one acting horizontal at the mid-span and the other acting diagonal from support A to joint at a point on the slanted side of right angle triangle.
Taking into account that the pined support is on the right and the roller on the left.
You are required to check the determinant and compute the reactions of this truss.

Help please :( - Flange Bolt coupling

By ladyaira0107@g… on

A flanged bolt coupling consists of two concentric bolt circles. One bolt circle consists of six 0.5-in-diameter steel bolts on a circle 9 inches in diameter and the other consists of eight 0.5-in-diameter steel bolts on a circle 12 inches in diameter. What is the shearing stress in the bolts if a torque of 7 kip-ft is to be carried by the assembly?

Normal shock wave

By Roland Joseph … on

1. Consider a NSW with a downstream-upstream temperature ratio of 3.5 what is the mach number upstream and downstream of the shock? Show your solution.

2. The flow just upstream of a NSW is at SSLC and the mach number downstream is 0.6152 determine the pressure, temperature, density, velocity, and the total pressure and temperature. Show your solution

3. The mach number behind of a NSW is 0.4752
What is the mach number in front of the wave and the pressure ratio across the shock? Show your solution.
