Worm gearsets are used for transmitting rotary motion between
Show Hint
Think about the relative angle between the two shaft axes and whether they actually cross in space.
Updated On: Jul 27, 2026
- non-parallel and non-intersecting shafts
- intersecting shafts
- parallel shafts
- non-parallel and intersecting shafts
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Recall how gear types map to shaft layouts.
Spur and helical gears connect parallel shafts. Bevel gears connect shafts whose axes intersect at a point, usually at 90 degrees. Worm and worm wheel sets connect shafts that are skew, meaning neither parallel nor intersecting.
Step 2: Picture the worm and worm wheel axes.
The worm looks like a screw and its axis sits perpendicular to the worm wheel axis, but the two axes lie in different planes and never cross, so they do not intersect.
Step 3: Match this to the answer choices.
Only "non-parallel and non-intersecting shafts" describes this skew arrangement; the other three options describe parallel or intersecting layouts that belong to other gear types.
Final Answer:
Worm gearsets transmit motion between non-parallel, non-intersecting shafts. \[ \boxed{\text{Answer: non-parallel and non-intersecting shafts}} \]

- A massive uniform rigid circular disc is mounted on a frictionless bearing at the end E of a massive uniform rigid shaft AE which is suspended horizontally in a uniform gravitational field by two identical light inextensible strings AB and CD as shown, where G is the center of mass of the shaft-disc assembly and g is the acceleration due to gravity. The disc is then given a rapid spin $\omega$ about its axis in the positive x-axis direction as shown, while the shaft remains at rest. The direction of rotation is defined using the right-hand thumb rule. If the string AB is suddenly cut, assuming negligible energy dissipation, the shaft AE will
- A structural member under loading has a uniform state of plane stress which in usual notations is given by $\sigma_x = 3P$, $\sigma_y = -2P$ and $\tau_{xy} = \sqrt{2}\,P$, where $P>0$. The yield strength of the material is 350 MPa. If the member is designed using the maximum distortion energy theory, then the value of $P$ at which yielding starts (according to the maximum distortion energy theory) is
- A square plate is supported in four different ways (configurations (P) to (S) as shown in the figure). A couple moment $C$ 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?
- A rope with two mass–less platforms passes over a fixed pulley. Each disc weighs 20 N. For $n=5$ and $m=0$, a downward force $F = 200$ N applied on the right platform (figure (i)) is just sufficient to initiate upward motion of the left platform. If the force $F$ is removed (figure (ii)), the minimum value of $m$ required to prevent downward motion of the left platform is ______________ (in integer).
- A rigid homogeneous uniform block of mass 1 kg, height $h = 0.4$ m and width $b = 0.3$ m is pinned at one corner and placed upright in a uniform gravitational field ($g = 9.81$ m/s$^2$), supported by a roller as shown. A short duration impulsive force $F$, producing an impulse $I_F$, is applied at a height $d = 0.3$ m from the bottom. Assume all joints to be frictionless. The minimum value of $I_F$ required to topple the block is ________________.

- A horizontal disk has a radial frictionless slot in which a small block is confined to slide. The disk turns anticlockwise about its centre with a constant angular velocity of 3 rad/s.
If the block slides along the slot with a constant speed of 0.2 m/s relative to the slot, then the magnitude of Coriolis acceleration in \( \text{m/s}^2 \) is - A gear train with five gears is shown in the figure below.
The number of teeth on each gear is \(N_1\), \(N_2\), \(N_3\), \(N_4\), and \(N_5\).

The engine rotates at a speed of 500 RPM in the clockwise direction if viewed from the front of the aeroplane. If the aeroplane while flying at 1200 km/hr turns with a radius of 2 km at same elevation, then the magnitude of the gyroscopic moment exerted by the rotor on the aeroplane structure in N m is
