Homework Statement
All variables are given in the pictures.
Homework Equations
Nothing more than simple force equations.
The Attempt at a Solution
I attempted it on my own, but I don't know if the answers are right.
Since you've included 7 problems in a single thread, an extended discussion of each will get jumbled. Much easier if you put them in separate threads. Or at least did one at a time.dwangus said:...how am I making this difficult?
This is good.dwangus said:Tension in second rope between 3kg and 4kg abbreviated as = T2
40 - T2 = 4a
T2 - 30 = 3a
a = 10/7
T2 = 240/7
Two rope segments pull down on the upper 4kg mass.T = T2 + mg
Problem 1: You're wrong.dwangus said:Like I said, can anyone just tell me if I'm right or wrong?
A force equation is a mathematical representation of the relationship between forces and other variables, such as mass and acceleration, in a physical system. It is used to calculate the magnitude and direction of a force acting on an object.
"All variables given in pictorial form" means that the equation is represented using visual symbols or diagrams instead of traditional algebraic notation. This can be helpful for understanding the physical meaning of the equation and solving problems graphically.
Force equations are based on Newton's laws of motion, which describe the relationship between forces, mass, and acceleration. The equations are used to apply these laws in specific situations and solve problems related to motion.
Yes, force equations can be used for any type of force, including gravitational, frictional, and electromagnetic forces. The specific equation used will depend on the variables given and the type of force being considered.
The units of force in a force equation are typically represented in newtons (N) in the SI system of units. However, other units such as pounds (lb) or dynes (dyn) may also be used, depending on the context. It is important to check and convert units when using force equations in calculations.
