FRICTION
Surfaces in contact are often assumed to be either frictionless (surfaces
can move freely with respect to each other)

Problem H2-6
MEAM 210, Fall 2015
Rods AB and BC are rigidly connected together to form the assembly shown. A 650 N load is applied at point C.
Determine the magnitude of the moment due to the 650 N force that acts about rod AB.

Problem H2-5
MEAM 210, Fall 2015
The four forces are applied to the plate as shown.
(a) Replace the loading shown with an equivalent resultant force and resultant moment at point D. Be sure to
specify magnitude and direction of both the resultant force an

Problem H2-1
MEAM 210, Fall 2015
Consider the 100 lb force that acts on the T-shaped bracket shown below. The objective of this problem is to calculate
the moment (magnitude and direction) about point A, which is where the bracket is anchored to the wall.

Problem H2-3
MEAM 210, Fall 2015
Consider the pipe assembly shown below. Determine the moment at point O due to applied force F.
(a) Use a scalar approach.
(b) Use a vector approach.

Problem H2-2
MEAM 210, Fall 2015
The tension in each cable (AB and BC) is 2000 lb. Determine the total moment about O caused by the tension in these
two cables.

Problem H1-1
MEAM 210, Fall 2015
Consider the I-beam trolley shown in the figure at the bottom. Such trolleys can roll along the flange of the I-beam and
are often used to move material in shops and industrial plants. Examples of an I-beam trolley and a h

Problem H1-2
MEAM 210, Fall 2015
Two cables are supported by three brackets, as shown below. Cable AB and AC are positioned as shown. Cable AC is in
tension and applies a 800 lb force, F, at support A.
(a) Write the force, F, as a Cartesian vector.
(b) De
