Step 1: Analyzing the Harappan cities.
Chanhudaro is well known for its focus on craft production and industrial activities, particularly bead-making and seal carving.
Step 2: Analyzing the options.
- (A) Harappa: Although Harappa was an important city in the Harappan civilization, it was not solely focused on craft production.
- (B) Mohenjodaro: Mohenjodaro was an important city, but it was not exclusively dedicated to craft production either.
- (C) Chanhudaro: This city was renowned for its craft production, particularly in bead-making and metalworking.
- (D) Rakhigarhi: This is a significant site but not specifically known for exclusive craft production.
Step 3: Conclusion.
The correct answer is (C) Chanhudaro, as it was mainly dedicated to craft production.
A weight of $500\,$N is held on a smooth plane inclined at $30^\circ$ to the horizontal by a force $P$ acting at $30^\circ$ to the inclined plane as shown. Then the value of force $P$ is:
A steel wire of $20$ mm diameter is bent into a circular shape of $10$ m radius. If modulus of elasticity of wire is $2\times10^{5}\ \text{N/mm}^2$, then the maximum bending stress induced in wire is:
