1 Spasms may affect many different types of muscles in the body, leading to many different symptoms and presentations. 2  Spasms of skeletal muscles are most common and are often due to dehydration and electrolyte abnormalities. 3  The spasm occurs abruptly, is painful, and is usually short-lived. If muscle spasms are especially painful, if they do not resolve or if they recur, medical care should be accessed to look for possible underlying causes. 2  Smooth muscles that are within the walls of hollow organs can go into spasm, causing significant pain.
When you want to attach wood to a steel I-beam, there are two acceptable ways to do it. The first and most traditional way is to pack the web between the I-beam flanges with multiple pieces of wood, then bolt them together. This is a very strong connection, but it wastes a lot of time and raw materials in the process.
Step 6 Calculate the shear strength of the selected beam, and check that the beam will support more shear load than is applied. Example #1 Select the lightest W-beam that will support a uniformly distrib-uted load of 3 kip/ft. on a simply-supported span of 20 ft.and de-flect no more than 0.6 inches. The beam is rolled high-strength, low-alloy steel (HSLA). Steps 1-4 The first few steps are identical to Example #1 because the beam loading and length are the same.ted load of 3 kip/ft. on a simply-supported span of 20 ft. and de-flect no more than 0.6 inches.
