Force is a quantitative description of an interaction that causes a change in an object's motion. An object mayspeedup, slow down, or change direction in response to a force. Put another way, force is any action that tends to maintain or alter the motion of a body or to distort it. O...
Forum:Introductory Physics Homework Help M Calculating tension in a wire holding beam against wall Hi, this is my first forum post - sorry if I'm in the wrong place, or I've done something wrong! Homework Statement Here goes: There is a beam of 0.5m length hinged to a wall at a rig...
However such a free-body\ndiagram of the forces on the pulley is not {\\it a priori} justified, inducing\nstudents to construct wrong hypotheses such as that the string transfers its\ntension to the pulley or that some symmetry is in operation. We reexamine this\nproblem by integrating ...
1、Force AP Physics Multiple Choice Name _1. In the situation below, what is the tension in string 1? a. 69.3 N b. 98 N c. 138.6 N d. 147.6 N e. 1.55 N 45125 kg2. Two masses, M and m, are hung over a massless, frictionless pulley as shown below. If M > m, what is ...
Calculate coefficient of friction on a car tire. Calculate ideal speed and angle of a car on a turn.Any force or combination of forces can cause a centripetal or radial acceleration. Just a few examples are the tension in the rope on a tether ball, the force of Earth’s gravity on the...
Forum:Introductory Physics Homework Help Tension of a pendulum and force components Homework Statement What is the tension in a pendulum? Is T=mgcos(theta) or is T=mg/(cos(theta)) ? and is the x component of tension is mgsin(theta) and this is the restoring force? Homework Equations Fn...
Find the accelerations of block S and block H, and the tension in the cord. Fundamentals of Physics Sample Problem 0 Mg N Ma T ) ( a m mg T N 13 m/s 8 . 3 2 mg m M M T g m M m a These two results make sense Fundamentals of Physics Sample Problem A cord pulls on a ...
In summary: Since the hanging mass is not moving, the net force on it must be 0. This means that the force due to gravity (weight) must be balanced by the tension force in the string. This is why Fg=18.1N in this situation. ...
Forum:Introductory Physics Homework Help P Static Equilibrium with buoyant force. High difficulty. Homework Statement I attached the original problem and a diagram I made with the variables on it. Basically we have a rod hanging from a wire at an angle theta with tension and the other end floa...
Because the outside diameter of the collar is larger than that of the pipe body, the flexural stress of the complete thread at the end of the API round thread or buttress thread casing in a crooked hole is the maximum, and the vulnerable spot of tension resistance is at the external thre...
