Assuming that all strands are vertical/ parallel to gravity and equally spaced (on a radius) around the centre of gravity then tension on each strand will be equivalent to weight x 9.81 divided by 7 equals tension in Newtons. If the strands are not normal and/or at varying distances from centre of gravity then it becomes a little more complicated. Summ of tension on strands must equal weight of bag. Tension on each strand is a ratio of it's distance from the COG of the furthest most strand. Don't forget the further from perpendicular a strand is the more tension on the strand.
the horizontal motion and the vertical motion are independent of each other
No, horizontal velocity and vertical velocity are independent and have no effect on each other.
The system that you describe is said to be statically indeterminate since, there are more than 2 wires (minimum required to support the cement bag with inclined support).There are three unknowns in the system that is the tensile forces in the wires. You should use three equations as follows to solve this.Vertical equilibrium: Sum of vertical components of tension in all wires is equal to the weight of 380NHorizontal equilibrium: Sum of horizontal components of tension in all wires add to zerCompatibility condition: The vertical component of elongation of all wires is the same.Formulate the three equations and solve the algebraic equation to get the tension in each wire.
If a picture is supported by two vertical strings, then the force exerted on each string is 25N.
Basic answer is that when twisting two ropes together you are causing tension in the fibers of the ropes as they bend around each other. If you don't secure both ends of the two ropes the tension will pull the ropes back to their relaxed state. Think of stretching out and wrapping a rubber band around your finger.
Opposite angles are the angles opposite each other on an x but vertical angles are the angles that are opposite and congruent.
If the ropes are perfectly vertical AND both of them are indeed sharing the load, then the tension in each rope is 5N. But it would be practically impossible to have them exactly share the load, and one would wind up supporting most or all of it. The best way to make them share is to use elastic ropes, like bungees. They still would never share equally, but at least they would share. In any case, the tensions in both support strands would always add up to 10N.
90 degrees
Adjacent angles will be right by each other and equal 180 degrees. Vertical angles will be opposite and equal to each other.
No. Vertical lines have the same direction but are not necessarily the same length.Therefore, two vertical lines will have the same angle but possibly not the same magnitiude.
Vertical angles have the same angle measure. Vertical angles are formed by two intersecting lines that look like an "x". Angles that are across from each other on this "x" are called vertical angles.
Vertically opposite angles are the angles that are opposite each other when two lines cross. Vertical means they share the same vertex.

Split the system first. Divide the weight based on the distance from the center of mass for a uniform solid. For each part of the system the force downward will be the the partial weight.Next, (this is easy if the ropes are vertical) you find the force on each rope by using trigonometry. The force on the ropes will be the hypotenuses of the triangle formed by the downward force and its angle.Notice that, as the angles (θ and θ') of the ropes approach 0° (horizontal), the force on the rope approaches infinity.
Given two intersecting lines, the two angles opposite each other have the same measure and are congruent.
This is a physic guestion . The topic is force.
