1

Fill in the blank: The allowance provided to a pattern for easy withdrawal from a sand mold is called ______.

Shake allowance

True or False: In sand casting, the pattern walls indicate boundaries where molten material is allowed.

False. Mould walls indicate boundaries within which the molten part material is allowed.

Riddle: I can be cylindrical or cubic, and I help in solidification slow and steady. What am I?

Riser

If the total solidification time of a cast product is 2.0 minutes, what will be the total solidification time for a cylinder under identical conditions?

2.83 minutes

Which type of support does not allow rotation and has reactions in horizontal and vertical directions?

Hinged/Pinned Support

Fill in the blank: The principle that states if three forces acting at a point are in equilibrium, then each force is proportional to the sine of the angle between the other two is known as ______.

Lami's Theorem

True or False: The resultant force acting on a body in equilibrium is non-zero.

False. The resultant force must be zero for equilibrium.

What is the main purpose of a free body diagram in mechanics?

To represent all forces acting on a body clearly and completely.

Riddle: I exist in a state where forces are balanced, yet I do not move. What am I?

An object in equilibrium
