In solid mechanics, shearing forces are unaligned forces pushing one part of a body in one specific direction, and another part of the body in the opposite direction. When the forces are colinear (aligned into each other), they are called compression forces. An example is a deck of cards being pushed one way on the top, and the other at the bottom, causing the cards to slide. Another example is when wind blows at the side of a peaked roof of a house - the side walls experience a force at their top pushing in the direction of the wind, and their bottom in the opposite direction, from the ground or foundation. William A. Nash defines shear force in terms of planes: "If a plane is passed through a body, a force acting along this plane is called a shear force or shearing force."
TL;DR Summary: Finding maximum bending moment on a boom
I am trying to solve the problem stated in the picture below.
The answers are given.
I've manage to find the Normal and Shear Forces but I'm stuck at the bending moment.
According to my analysis the maximum bending moment is +7208,1...
I am looking for some help. I have completed the question below. I will show my answers.
I believe this to be correct. If it is not would appreciate someone letting me know so i can correct.
Now i am attempting this question:
Could anyone help, or point me in the...
I have used this forum a few times and it has been very helpful, however now I am stuck. I have completed the question above however I have conflicting information regarding the Tensile and Shear force being applied to the rivet. I use the following calculation for this:
I know that shear stress in horizontal beams has a parabolic distribution, so that the max shear stress occurs at the neutral axis. I also understand that for a beam subject to a distributed load with supports at its ends, the magnitude of the shear force is highest at the left and right ends of...
I am having a headache to try understand a possibly simple real-world problem: efficiency (as in number of strokes/cumulative length needed) to saw steel, assuming a constant sawing length per stroke and a known steel sectional area.
I began to think about the few assumptions I assume...
If I have a catheter covered in a thin sheathe (think a cylinder, covered by a thin plastic film), how should I go about calculating the shear force it takes to unsheathe the catheter from the sheath (no torque here, just the catheter moving in and out)? I've thought about strain gauges (but...
I'm programming a game in which I'd like to simulate the real world physics of an attack using primarily medieval style weapons. Think dwarf fortress, but rather than assigning damage numbers we're calculating force or kinetic energy. Getting that much is easy enough since I can find the mass of...
1)In a flowing fluid in laminar fashion we know that it flows in planes which slides over each other, Let's take a fluid element (cylindrical) in a pipe(Radius=R) the resistive force is (stress)(cross section area of cylinder with radius 'r') acting in backward direction, now if I take Flow...
1. Homework Statement
I have problem solving the bending moment and shear force of a conduit with a curve end. The conduit is lifted in the mid-air with 2 slings and assume it is in equillibrum.
I have attach a drawing for reference.
What i know, there is a UDL somewhere...
Homework Statement [/B]
The inclined ladder AB supports a house painter (85 kg) at C and the self weight (q = 40 N/m) of the ladder itself. Each ladder rail (tr = 4 mm) is supported by a shoe (ts = 5 mm) which is attached to the ladder rail by a bolt of diameter dp =8 mm.
1) Find support...
The orange thing is a gear being turned by a motor, which is intended to move the frame the shaft is fixed to. I realize the applied torque is going to create support reactions, but I can't quite figure out how to calculate the needed material strength so that the frame won't shear.
I have simplified the problem down to something like a physics textbook question, although this is a practical problem where the pivot on my rotary actuator has been damaged by a faulty driver which caused the armature to ram into the endstop.
Obviously this needs better protection. My problem...
Basically I need to find the shear force and bending moment of a beam using octave. The length of the beam as well as forces and their distances are given. However the SF and BM must be calculated at every o.ooo5m. The forces can be Point Loads or Uniform Distributed Loads and there can...
In the image uploaded below, a boxed shaped object is shown. It is floating in water so the forces that act on it are buoyancy and gravity. The first and the last compartments are filled with evenly distributed weight. The middle 2 compartments are empty.
Force by uniform loading = 20(5) = 100kN
Vertical component of the uniform loading = 20(5)(3/5) = 60kN
Horizontal component of the loading = 20(5)(4/5) = 80kN
vertical reaction at roller support = Vr
vertical reaction at pin support = Vp
Im struggeling with understanding this task. Yeah I'm an amateur.. My English is not that good as well. My main problem is understanding where the share forces act on this dam, if its through the centre of pressure, or if its at the bottom of the dam. Now I have calculated the share forces...
I have a disk of diameter of 150mm and thickness of 10mm which is rotating at the constant speed of 100rpm. The disk is inside water which is approximately 4-5 cm below the surface. Disk is horizontal (parallel to the water surface). Disk is attached with the shaft of the motor. At...
I'm working on a homework problem for Statics and I'm stuck. Could someone please help?
Problem: Draw the internal force (N,V,M) diagrams and include all significant figures
Here is all of my work:
Resulting F from W1:
W(x) = W1
∴ F2=∫02b W1dx
eq (1) ⇒ F2 = W1⋅2b
x1 = (F1)-1 ∫02b W1dx...
Can someone help me with determining the free body force diagram, and hopefully I can go on from there.
M = F.d
I found T = 500N
The answers are shear force = -62.5N , Moment = 64.4 Nm , Tension = 500N
