A rod is bent into an L shape and attached at one point to a
pivot. The rod sits on a frictionless table and the diagram is a
view from above. This means that gravity can be ignored.
If F3=0 and F1=12N, what does the magnitude of F2 have to be for
there to be rotational equilibrium?
If the L-shaped rod has a moment of inertia
I=9 kg m2), F1=12N, F2=27, , and again F3=0, how long a time t...

To understand the two most
common procedures for finding torques when the forces and
displacements are all in one plane: the moment arm method and the
tangential force method. The purpose of this problem is to give you
further practice finding torques in two-dimensional situations. In
this case it is overkill to use the full cross product definition
of the torque because the only nonzero component of the torque is
the component perpendicular to the plane containing the problem.
There...
In the figure, a block weighing 22.0 N is held at rest against a
vertical wall by a horizontal force F→ of magnitude 60 N. The
coefficient of static friction between the wall and the block is
0.55, and the coefficient of kinetic friction between them is 0.38.
In six experiments, a second force P→ is applied to the block and
directed parallel to the wall with these magnitudes and directions:
(a)33 N, up, (b)11 N, up,
(c)48 N, up,...

Moment of a Force-Vector Formulation Learning Goal To use the vector cross product to calculate the moment produced by a force or forces, about a specified point on a member The moment of a force F about the moment axis passing through O and perpendicular to the plane containing o and F can be expressed using the veotor cross product, Mo x F. n a properly constructed Cartesian coordinate system he vector cross product can be...
When an atom is placed in an external field, the nucleus moves just a tiny bit, so that it is no longer centered, until it is once again in equilibrium As a result, the atom acquires a dipole moment. For many atoms, the induced dipole moment is proportional to the applied field; these are called linear materials, or dielectrics. This dependence, called the polarizability, can be measured fairly easily in the lab. Remarkably, Gauss’s law is all we need to...

A positive internal shear force V • acts downward on the right-hand face of a beam. • acts upward on the left-hand face of a beam. A positive internal bending moment M • acts counterclockwise on the right-hand face of a beam. • acts clockwise on the left-hand face of a beam. = = Use the graphical method to construct the shear-force and bending-moment diagrams for the beam shown. Label all...
1. In this exercise, you will analyze the supply-demand equilibrium of a city under some special simplifying assumptions about land use. The assumptions are: • all dwellings are situated within apartment complexes, • all dwellings must contain exactly 1,500 square feet of floor space, re- gardless of location, and • apartment complexes must contain exactly 15,000 square feet of floor space per square block of land area. These land-use restrictions, which are imposed by a zoning authority, mean that dwelling...
