Spring element

Example 01. For the spring assemblage with arbitrarily numbered nodes shown in the figure
obtain (a) the global stiffness matrix, (b) the displacements of nodes 3 and 4, (c) the
reaction forces at nodes 1 and 2, and (d) the forces in each spring. A force of 5000 lb
is applied at node 4 in the x direction. The spring constants are given in the figure.
Nodes 1 and 2 are fixed.

Shipwrecks – Surfing in an Aquarium – Nusa Lembongan – RAWFILES – 07/NOV/2021 – 4K


The wave has changed since the latest shipwreck washed up on the reef in September 2021. Shipwrecks got its name when the first ship sunk around the 70’s and took ten year to disintegrate on the reef. Some backwash at the takeoff (on a small day) and one peak that’s disappeared but other than that, the main wave is still amazing and one of the best righthanders around Bali/ Lembongan.
Super glassy conditions, mid to high to mid tide made it 6 hours plus to be able to surf the wave this day, so if you timed your surfing well, the crowd was only 34 people.
Riders in Appearence:
Putu , Robot, Giadalegati, Wala, Pulu
