Question 27
Open questionMEMCQ1 markNeeds review
A rigid massless tetrahedron is placed such that vertex O is at the origin and the other three vertices A, B, and C lie on the coordinate axes as shown in the figure. The body is acted on by three point loads, of which one is acting at A along x-axis and another at point B along y-axis. For the body to be in equilibrium, the third point load acting at point O must be

A square plate is supported in four different ways (configurations (P) to (S) as shown in the figure). A couple moment
is applied on the plate. Assume all the members to be rigid and mass-less, and all joints to be frictionless. All support links of the plate are identical.

The square plate can remain in equilibrium in its initial state for which one or more of the following support configurations?
Your answerSelect all correct options. You can choose more than one.

Two rigid massless rods PR and RQ are joined at frictionless pin-joint R and are resting on ground at P and Q, respectively, as shown in the figure. A vertical force
acts on the pin R as shown. When the included angle
, the rods remain in static equilibrium due to Coulomb friction between the rods and ground at locations P and Q. At
, impending slip occurs simultaneously at points P and Q. Then the ratio of the coefficient of friction at Q to that at P (
) is _________ (round off to two decimal places).

A slider crank mechanism is shown in the figure. At some instant, the crank angle is 45° and a force of 40 N is acting towards the left on the slider. The length of the crank is 30 mm and the connecting rod is 70 mm. Ignoring the effect of gravity, friction and inertial forces, the magnitude of the crankshaft torque (in Nm) needed to keep the mechanism in equilibrium is __________ (correct to two decimal places).
