1. **Determine the Throat Thickness (t):**
 t = k \cdot a  
 k = 0.707  
 a = 0.6 \, \text{cm}  
 t = 0.707 \times 0.6 = 0.4242 \, \text{cm}  
2. **Calculate the Weld Area (A):**
 A = t \times L  
 t = 0.4242 \, \text{cm}  
 L = 1 \, \text{cm}  
 A = 0.4242 \times 1 = 0.4242 \, \text{cm}^2  
3. **Calculate Welding Resistance (Rs):**
 R_s = F_y \times A  
 F_y = 4921.5 \, \text{kg/cm}^2  
 A = 0.4242 \, \text{cm}^2  
R_s=4921.5\times0.4242\approx2087.70\,\text{kg/cm} 
**Final Answer:**
R_s\approx2087.70\,\text{kg/cm}
