6. A part of the structure for a factory automation system is
a beam that spans 30.0 in as shown in Figure P5-6. Loads
are applied at two points, each 8.0 in from a support. The
left load F₁ = 1800 lb remains constantly applied, while
the right load F₂ = 1800 lb is applied and removed fre-
quently as the machine cycles. Evaluate the beam at both
B and C.

30. Repeat Problem 28, except using a shaft that is rotating
and transmitting a torque of 150 N⚫m from the left bear-

It sees a load that varies from a tensile force of 20.0 kN to a compressive force of 8.0 kN.arrow_forwardfind stress at Qarrow_forwardI had a theoretical question about attitude determination. In the attached images, I gave two axis and angles. The coefficient of the axes are the same and the angles are the same. The only difference is the vector basis. Lets say there is a rotation going from n hat to b hat. Then, you introduce a intermediate rotation s hat. So, I want to know if the DCM produced from both axis and angles will be the same or not. Does the vector basis affect the numerical value of the DCM? The DCM formula only cares about the coefficient of the axis and the angle. So, they should be the same right?arrow_forward

A particle of mass m slides down the tube under the action of gravity. If there is a coefficient of friction μ between the tube and the particle, what is the steady-state speed of the particle? Let y γ 30° and assume that µ < 1/√3.arrow_forwardThe plate is moving at 0.6 mm/s when the force applied to the plate is 4mN.

Determine the stress in the steel and in the copper when the temperature of the bar is raised by 80°C and an axial tensile force of 60 kN is applied.

A particle of mass m is embedded at a distance R from the center of a massless circular disk of radius R which can roll without slipping on the inside surface of a fixed circular cylinder of radius 3R. The disk is released with zero velocity from the position shown and rolls because of gravity, all motion taking place in the same vertical plane. Find: (a) the maximum velocity of the particle during the resulting motion; (b) the reaction force acting on the disk at the point of contact when it is at its lowest position.
