Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

Question

A homogeneous block of height 0.4 m, width 0.3 m
and weight 521 N is put on a rough horizontal surface
and connected to a block of weight W through a
massless inextensible string AD as shown. The string
passes over a rough circular fixed surface and contacts
it over the portion BC. The portion AB of the string
makes an angle of 30 deg with the horizontal, and the
coefficient of static friction on all contacting surfaces is
u=0.4. Calculate the maximum value of W (in N) for
which static equilibrium is maintained (answer correct
to 1 place of decimal).

Figure(a) depicts a head-on view of a 1000 kg mass private airplane flying in a state of equilibrium. The force labeled P represents the lift force acting on each wing, and W represents the gravitational weight of the craft. Fig. (b) depicts a more detailed view of the wing ABCD showing its physical dimensions and the assumed location of the lift force P. The wing has a mass of 200 kg and a center of gravity at point B. The wing is attached to the fuselage at point A, which can be modeled as a pin connection. The wing is supported by a pin-connected strut BE whose mass may be neglected. (a) Sketch a free-body diagram of the forces acting on the wing depicted in Fig (b). Compute the vertical lift force P. (c) Compute the forces supported by the strut BE and the pin at A. Hint: You may model the wing as a two-dimensional structure where all forces lie in the same plane. (a) P XERO y W (b) 1.4 m + 2 m B с 0.6m 2.4m D
A horizontally positioned door weighing 1200 N is held in place by hinges centered at points A and B and a taut rope stretched between points D and E. The hinges facilitate "smooth" rotation about the x-axis, and point C coincides with the door's center of gravity. Questions: (a) Sketch a free-body diagram of the door, showing all possible forces and reactions exerted on the door. (b) Is the problem statically determinate or indeterminate in its current form? Jus- tify your answer. (c) If the hinge at point B is broken and physically disconnected from the door, such that the door is now only supported at points A and D, is the problem statically determinate or indeterminate?

A non-uniform bar rests across two supports that are 20 ft apart. When loads of 200 lb, 4 ft from end A and 150 lb, 6 ft from end B, are on the bar, end A supports 233 lb and end B supports 197 lb. Find the weight of the bar and the position of the center of gravity.
A student suspends a chain consisting of three links, each of mass m = 0.210 kg, from a light rope as shown in (Figure 1). The rope is attached to the top link of the chain, which does not swing. She pulls upward on the rope, so that the rope applies an upward force of 9.50 N to the chain. (I) Draw a free-body diagram for the entire chain, considered as an object, and one for each of the three links. (II) Use the diagrams of part (I) and Newton's laws to find (i) the acceleration of the chain, (a) the force exerted by the top link on the middle link, and (b) the force exerted by the middle link on the bottom link. Treat the rope as massless. (III)There are four objects of interest in this problem: the chain as a whole and the three individual links. For each of these four objects, identify the external forces acting on them. Besides the force of gravity, you should include only forces exerted by other objects that touch the object in question.
