Chapter 3, Problem 3.19P
A typical World War I biplane fighter (such as the French SPAD shown in Figure 3.50) has a number of vertical interwing struts and diagonal bracing wires. Assume for a given airplane that the total length for the vertical struts (summed together) is 25 ft. and that the struts are cylindrical with a diameter of 2 in. Assume also that the total length of the bracing wires is 80 ft. with a cylindrical diameter of

Which of the which of the legs supports about half of the table's weight?
O The far leg
O The left leg
None. Each supports close to one-third of the table's weight.
O The right leg
None. Each supports approximately the entire tabe's weight.
Two builders carry a sheet of drywall up a ramp.
Assume that W = 1.9 m, L = 3.3 m, theta = 19.0⁰, and
that the lead builder carries a weight of 109.0 N (24.5 lb).

What is the weight carried by the builder at the rear?
HINT: Consider the drywall to have no thickness.
The builder at the rear gets tired and suggests that the
drywall should be held by its narrow side.
~W~
0
What is the weight he must now carry? HINT: From the
previous problem, you know how much each builder
carries. Therefore you know the total weight. Set the
sum of the torques about the front lower corner to 0, so
that you do not need to know the weight carried by the
builder in front.

- Urgentarrow_forwardProblem 4.30 While the stiffness of an elastic cord can be quite constant (i.e., the force versus displace- ment curve is a straight line) over a large range of stretch, as a bungee cord is stretched, it softens; that is, the cord tends to get less stiff as it gets longer. Assuming a soften- ing force-displacement relation of the form k8 - B83, where 8 (measured in ft) is the displacement of the cord from its unstretched length, considering a bungee cord whose unstretched length is 150 ft, and letting k = 2.58 lb/ft, determine the value of the con- stant B such that a bungee jumper weighing 170 lb and starting from rest gets to the bottom of a 400 ft tower with zero speed.arrow_forwardTwo weights are connectedby a very light, flexible cord that passesover an 80.0 N frictionless pulley of radius0.300 m.
