2 answers:

6 0

Red platelets depend on glucose for energy and convert glucose to lactate. The cerebrum utilizes glucose and ketone bodies for energy. Fat tissue utilizes unsaturated fats and glucose for energy. The liver principally utilizes unsaturated fat oxidation for energy

What is the magnitude of the force exerted by the biceps fbiceps? What is the magnitude of the force exerted by the elbow felbow

Slav-nsk [51]

Answer:

The magnitude of the force exerted by the biceps $f_b_i_c_e_p_s$ is 218.38N

The magnitude of the force exerted by the elbow $f_e_l_b_o_w$ is 194.37N

Explanation:

Firstly , lets calculate the magnitude of force exerted by biceps $f_b_i_c_e_p_s$ -

Mass of the forearm=

$m_f=1.50kg$

Mass of the ball =

$m_b_a_l_l=950g$

= 0.950kg

so, weight of the forearm=

$w_f=m_f$ g

weight of the ball=

$w_b_a_l_l=m_b_a_l_l$ g

Now , balancing torque about the elbow , we have-

$F_b_i_c_e_p_s\times d_b_i_c_e_p_s= w_f\times\frac{d_b_a_l_l}{2} + w_b_a_l_l\times d_b_a_l_l$

(here , distance of the bicep is 2.50cm = 0.025m and distance of the ball is 36cm= 0.36m)

Now putting the given values in the formula -

$F_b_i_c_e_p_s\times 0.025= 0.95\times9.8\times\frac{0.36}{2} +1.50\times 0.36$

$F_b_i_c_e_p_s=218.38N$

Now, lets calculate the force exerted by elbow $F_e_l_b_o_w$ -

Balancing the vertical forces

$F_b_i_c_e_p_s=F_e_l_b_o_w+w_f+w_b_a_l_l$

$F_e_l_b_o_w = 218.38-(1.00\times9.8)-(0.95\times9.8)$

$F_e_l_b_o_w=194.37N$
