An elastic cord can be stretched to its elastic limit by a load of 2 N. If a 35 cm length of the cord is extended 0.6 cm by a force of 0.5 N, 37.4 cm is the length of the cord when the stretching force is 2.5 N.

What is the calculation of the length?

Elastic cord has a limit of 2 N, It can be stretched to .6 cm with a force of .5 N

Need to find elastic cord’s constant:

Force(F) = extension(e) x constant(k)

.5 = .6 x k, ==> k = 5/6 N/cm or  ≈

.833 N/cm

>>>>>>>Finding the extension without limit:

2.5 = e x 5/6, ==> e = 3 cm

Thus, this cord could be stretched (35 + 3 = 38) 38 cm

>>>>>>>But, you have a max limit of 2 N:

2 = e x 5/6, ==> e = 2.4

This cord can be stretched up to (35 + 2.4 = 37.4) 37.4 cm

Explanation:

In the SI prefix, the value of 2000 W is also written as 2 kW. This is because 1 kW = 1000 W.

SI prefixes may be defined as a collection or sequence of prefixes to units in the International System of Units, or SI. These can denote very small or very large amounts.

These types of prefixes are most commonly utilized in computing to refer to storage space, such as bytes, even though storage is not an official SI unit.

The designations of multiples and subdivision of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth.

Therefore, in the SI prefix, the value of 2000 W is also written as 2 kW. This is because 1 kW = 1000 W.

1.0 ns clock cycles are needed to complete the task or it is needed to run a clock for 24hrs if it uses 50mA per second.

This is the reciprocal of the clock frequency. For example, a 1 GHz processor has a cycle time of 1.0 ns, and a 4 GHz processor has a cycle time of 0.25 ns.

Divide the clock cycles by one to determine the length of the clock cycle. One clock cycle equals 1/(1 * 10^6 cycles/sec) or 1/1 * 1/(10^6 cycles/sec). . A power above 1 reverses the units and signs, so 1/10^6 cycles/second is 10^-6 seconds/period.

Therefore, 1.0 ns clock cycles are needed to complete the task or it is needed to run a clock for 24hrs if it uses 50mA per second.

For truss bridges, the maximum load bearing capacity can be determined using the equations of equilibrium and the method of joints.

Equilibrium is a state of balance in a system, where all forces and influences are equal and in balance. It occurs when the opposing forces in a system cancel each other out, thus creating a state of rest or stability.

This involves calculating the sum of all the forces in the vertical and horizontal directions, and then using the equations of equilibrium to determine how much force each member of the truss is supporting.
For arch bridges, the maximum load bearing capacity can be determined using the equations of equilibrium and the method of sections. This involves calculating the sum of all the forces in the vertical and horizontal directions, and then using the equations of equilibrium to determine how much force each member of the arch is supporting. Additionally, the bending moment of the arch can be calculated by taking the moment of the forces applied to the arch about an arbitrary point.
For beam bridges, the maximum load bearing capacity can be determined using the equations of equilibrium and mechanics of materials. This involves calculating the sum of all the forces in the vertical and horizontal directions, and then using the equations of equilibrium to determine how much force each member of the beam is supporting. Additionally, the bending moment of the beam can be calculated by taking the moment of the forces applied to the beam about an arbitrary point. The maximum bending moment of the beam can then be determined by using the equations of mechanics of materials.
