英语翻译Shear strength refers to how well a member can withstand two equal forces acting in opposite directions.Fatigue strength is the property of a material to resist various kinds of rapidly alternating stresses.For example rod or an axle unde
25. Two equal forces acting on an object in opposite directions will be in equilibrium D A only if they act on the same point on the object. B if they are separated by a distance. C when they are balanced by a third force. D when their moments about the same point are equal. 相...

Tensile stress is a result of two forces acting in ___. A.opposite directions on the same line,tending to pull the material apart B.opposite directions on the same line,tending to compress the object C.opposite directions along parallel lines D.the same direction along parallel lines答案 ...
By this arrangement, whereby lineal forces acting in opposite directions through each of the units, a single couple constituting a single force by the aligned hook components, an equilibrium is produced. Equilibrium is produced relative to the lineal force or forces radiating from the central ...
2-26. If the resultant FR of the two forces acting on the log is to be directed along the positive x axis and have a magnitude of 10 kN, determine the angle 8 of the cable,attached to B such that the force F B in this cable is minimum. What is the magnitude of the force in...
B。解析:For example, in a collision between two objects, as long as there are no external forces acting on the system, the total momentum of the two objects before the collision will be the same as the total momentum after the collision.(例如,在两个物体的碰撞中,只要没有外力作用在系统上...

A system of forces acting on a body is in equilibrium if: 1. **The vector sum of the forces is zero.** This means the net force acting on the body is zero, ensuring no linear acceleration. 2. **The sum of the moments of the forces about any point is zero.** This means the ...
