Question 6 0.5 points Save Answer • Shown in the figure below is a solid cylinder. The x-axis is along the longitudinal direction. The angle is measured with respect to the x-axis, positive if counterclockwise, i.e. towards the y-axis as shown below, and negative if clockwise. 01 and 02, with principal stresses, and Tmax is maximum shear stress. 012021 are the Fractute surface Normal to Fracture surface Suppose that the cylinder is subjected to a uniform tensile stress of 5000...
The figure below shows a human arm that weighs 39.3 N. The arm
is extended outward and is motionless. The gravitational force
Fg
on the arm acts at point A, a distance of 0.290 m from
the shoulder joint, which is represented by point O. The
shoulder pushes down and to the right on the humerus bone of the
arm with a force
Fs
at point O, at an angle θ as shown. The
deltoid muscle pulls back on the...

The figure below shows four positive point charges q1= q2= q3= q4= +2 muC. A fifth (negative) charge q5= -1 muC is located at the origin. Calculate the net electric force acting on the fifth charge. Charge q4 can be moved along the Y-axis. To what y-value must charge q4 be moved to rotate the direction of the net electric force on charge q5 by 45 degree counterclockwise? Calculate the net electric...
Three charges are arranged as shown in the figure below. Find
the magnitude and direction of the electrostatic force on the
charge q = 5.14 nC at the origin. (Let
r12 = 0.230 m.)
Three point charges lie along the axes in the x
y-coordinate plane.
Positive charge q is at the origin.
A charge of 6.00 nC is at (r1 2, 0), where
r1 2 > 0.
A charge of −3.00 nC is at (0, −0.100 m).

The solid cast-iron post shown in the figure below is lightly buried in the soil at point B.Its diameter d is d= 0.04 m, and length lis 1=0.6 m. If a torque is applied to its top using a rigid wrench, determine the maximum shear stress in the post and the angle of twist at its top. The magnitude of the force couple Fis F= 200 N. Assume that the torque is about to turn the post,...
Consider a system of three point charges as indicated in the
figure below, where an x-axis and y-axis are shown as reference in
the system. The coordinates of these charges are given as follows:
?1(0,0), ?2(d,0), and ?3(d,d). The charges ?1 and ?3 are positive,
whereas the charge ?2 is negative.
a) Express the resultant force ?⃗ 3 exerted on ?3, in terms of ?1,
?2, ?3, and d, in unit vector notation. Show all vectors on the
figure, and...
