What does the first mechanics school work in the 1st grade HTL look like?

We have topic: -Torque -statistical moment -offset moment -Clearing/cutting free components -Equilibrium conditions of mechanics -level/spatial force system -Torque calculations using the formula M=rx F -Kinematics and dynamics (statics, kinetics) -Support reactions (cables, bars, 1, 2, 3-valued supports,…) What might such a school assignment look like, and how many tasks would typically be included? Could…

Why does the direction of the force in the rope point downwards and not upwards, when the force actually pulls the body upwards?

I mean, the downward gravitational force isn't always the same as the tensile force pulling the body upward, is it? And I know a rope only absorbs tensile forces, but then the force has to be drawn on the cable drum and not on the rope, because the downward force is the gravitational force, and…

What is this condition and does it go away with time?

I feel like I'm constantly teetering on the edge, teetering on the edge of bad feelings and circling thoughts. One moment I feel completely normal, and suddenly I feel, see, and experience everything much more intensely or in a dull way. Then I find it difficult to analyze my surroundings and perceive everything evenly. A…

What are your best unforgettable moments in life?

For me, unforgettable moments are those in which I experience the following: I'm in Tyrol, at Innsbruck Airport, in the first-class lounge, enjoying my coffee with a view of the mountains. Meanwhile, I'm reading my emails, in which the CEOs of Repsol and ENI invite me for coffee. Many executives invite me to their countries…

How would you react to the growling as the owner of your four-legged friend if you wanted to give your dog a shower?

She rolls around in animal droppings from rabbits, horses or other wild animals, so she smells extremely bad and needs to be showered, just to let you know. So, I turn the water in the shower on and make it warm before I get the dog out of bed to shower. The moment I want…

How do I get the results? It is clear that for the moment R, for example, the forces C and A do not act, but how do I get FB?

Why 2 × a × FB + 1 × a × F? Where do the length measurements come from, why 2 times a? And for moment S, why -1.41 × a? Is it because of the diagonal or because the force is divided?
