can you explained the question step by step because everyone solve this questions different ways and calculations.Thank you..

In an open die forging operation, a starting billet with a cylindrical shape is going to be used. The diameter and the height of the billet are 100mm and 150mm, respectively. The coefficient of friction between the billet and the die surface is estimated as 0.5 . Assuming a non-ideal (non-homogeneous) deformation, can the billet be forged if the maximum capacity of the press is; a) 10 tonnes? [5 pts] b) 50 tonnes? [5 pts] c) 100 tonnes? [5 pts] Note: vield and UTS of the billet material is 25MPa and 100MPa, respectively
